NATIONAL LEVEL OFFLINE TEST
The Elementary Mathematics section in UG CLAT 2020 will roughly contain around 13-17 questions. Each question has a weight of 1 mark. 0.25 marks will be deducted for each incorrect answer. Candidates may note that this section is based on the mathematical concepts of class 10 which are relatively easy to deal with. The candidates can appear for various mock tests and solve the sample papers carefully in order to prepare themselves for the examination.

When it comes to preparing for CLAT, it is very easy to lay your hands on online resources. There are many websites which provide study materials and notes to the students. Many organisations also conduct online mock test to help the students prepare for the examination. These mock tests contain section-wise questions to help the students analyse their preparations. Here are a few websites which are highly recommended for CAT preparation:
The candidates can go through more CLAT Practice Papers and prepare better for the exam.
One of the most important and scoring sections of the CLAT examination is the Elementary Mathematics part. This section contains only basic questions which can be easily solved with fundamental concepts of mathematics.
Here are few pieces of advice which the students will find useful while studying for CLAT:
Ques 1. Sang-Saath Bank’s employees’ picnic on a river island turned into a disaster as the newly constructed road bridge connecting the island to the riverbank collapsed. Evacuation operations had to be carried out by ferrying the employees from the island across the river and on to the riverbank. One-sixth of the employees were evacuated by villagers in a country boat. Of the remaining, one-fifth were evacuated by fishermen in a trawler. The remaining evacuees were joined by villagers who were helping with the evacuation. Finally, 8 motor boats with 8 people each left the island.
1.1 If half of the motor boats had one villager each and the other half had 2 each, what was the ratio of villagers to employees in the motor boats?
Rationale: The correct answer is (2). Number of people that left on the 8 motor boats = 8 * 8 = 64 (i) Half of 8 boats had 1 villager each = ½ * 8 * 1 = 4 … (ii) Half of 8 boats had 2 villagers each = ½ * 8 * 2 = 8 … (iii) Therefore, total number of villagers = y = (ii) + (iii) = 4 + 8 = 12 (iv) Therefore, total number of employees in the 8 motor boats = (i) + (iv) = 64 – 12 = 52 (v) Therefore, ratio of villagers to employees in the 8 motor boats = (iv) : (v) = 12:52 = 3:13
1.2 How many employees were evacuated in the trawler?
Rationale: Number of employees evacuated by the country boat = x/6 (vi) Remaining employees after country boat evacuation = x – x/6 = 5x/6 (vii) Number of employees evacuated by the trawler = 1/5 * 5x/6 = x/6 (viii) [Note: See Rationale for 1.1 for calculated data] From (v) in Rationale for 1.1, we know that the number of employees evacuated by the 8 motor boats = 52.
Therefore, 52 = Remaining employees after country boat evacuation - Number of employees evacuated by the trawler, i.e. (vii) – (viii) = 5x/6 – x/6 = 4x/6 = 2x/3 Therefore, x = 52 * 3/2 = 78 = Total number of employees Therefore, the number of employees evacuated by the trawler = 78/6 = 13
1.3 If there were 4 villagers in the country boat, and 6 fishermen in the trawler, and if an equal number of people travelled in each trip; i.e. country boat, trawler, and motor boats, how many people travelled in each trip?
Rationale: Total number of employees = 78 [Note: See Rationale for 1.2] Villagers and fishermen in the country boat and trawler = 4 + 6 = 10 Number of villagers in the 8 motor boats = 12 [Note: See (iv) of Rationale for 1.1] Total number of people that travelled = 78 + 12 + 10 = 100 Number of trips = 1 (country boat) + 1 (trawler) + 8 boats = 10 Average number of people travelled by the country boat, trawler and the last 8 boats = 100/10 = 10
1.4 After they reached the shore, 1/3 of the employees took a taxi, half of them took a bus and the remainder took the train. The cost of a hiring a 4-seater taxi was Rs.500, the cost of hiring a bus was Rs.5000 and each train ticket was priced at Rs.75. The taxis took a maximum of four passengers each. If the total expenditure on the different modes of transport was Rs.9,475, how many taxis were hired?
Total number of employees = 78 [Note: See Rationale for 1.2] Number of employees that took a taxi = 1/3 * 78 = 26 Since each taxi is only a 4-seater, the number of taxis needed = 26/4 = 6 1/2 Therefore, number of taxis hired = 7
1.5 The total number of employees in Sang-Saath Bank is 4.5 times the number that went on the picnic. The Securities department of the bank consists of 4/9 of the total number of employees. The percentage of Sang-Saath Bank’s employees in the Securities department is:
Rationale: Total number of employees evacuated = 78 [Note: See Rationale for 1.2] Total number of employees in the bank = 4.5 * 78 = 351 Number of employees in securities = 4/9 * 351 = 156 Percentage of people in Securities = 156/351 * 100 = 44.44%
