Question 3

If 9@7=4; 6@1=10; 7@4=6; then what is the value of 8@2=?

Accepted Answer

The pattern is (First number - Second number) × 2. So, (9-7)×2 = 4 and (6-1)×2 = 10. Applying this, (8-2)×2 = 12.

Question 4

The production of company 1 in year 2014 is 18000 and sales of company 2 in year 2012 is 15000. What is the ratio of difference in sales and production of company 1 in year 2014 and company 2 in year 2012?

Accepted Answer

Extract the sales and production values for both companies from the given data. Calculate the difference for Company 1 in 2014 and Company 2 in 2012, then find their ratio to get 8:15.

Question 5

A sum amounts to Rs 7727.104 at the rate of 12% per annum compounded annually after three years. What is the value of principal (in Rs)? ?

Accepted Answer

Use the formula A = P(1 + R/100)^n. Here, 7727.104 = P(1.12)^3. Since 1.12^3 = 1.404928, dividing 7727.104 by 1.404928 gives the principal P = 5500.

Question 7

What is the area (in sq cm) of a rhombus if the lengths of its diagonals are 25 cm and 20 cm?

Accepted Answer

The area of a rhombus is half the product of its diagonals. Area = (1/2) × d1 × d2 = (1/2) × 25 × 20 = 250 sq cm.

Question 8

Improve the bracketed part of the sentence. When I first saw Ankit, he (was playing) cricket.

Accepted Answer

The past continuous tense 'was playing' correctly describes an ongoing action in the past when another action (seeing Ankit) occurred. No improvement is needed.

Question 9

What is the area (in sq cm) of a rectangle if its diagonal is 26 cm and one of its sides is 10 cm?

Accepted Answer

Using Pythagoras theorem, the other side is √(26² - 10²) = √576 = 24 cm. The area of the rectangle is length × width = 10 × 24 = 240 sq cm.

Question 10

Even if memory of model D was halved it would be greater (in %) than that of model B by?

Accepted Answer

Assuming Model B's memory is 1 unit, the halved Model D memory is 4 units. The difference is 3 units. Percentage greater = (3/1) × 100 = 300%.

Question 11

A man starts running from point P at 11:00 a.m. with a speed of 10 km/hr. He runs for 2 hours and then takes a 1 hour rest. He continues this till he is caught by another man who starts at 2:00 p.m. from point P and runs non-stop at a speed of 15 km/hr towards the first man. At what time (in p.m.) will the first man be caught?

Accepted Answer

By 4:00 p.m., the first man covers 40 km and starts resting. The second man covers 30 km. The second man covers the remaining 10 km in 40 minutes, catching him at 4:40 p.m.

Question 12

If I walk at 7/6 of my usual speed, then I reach my ofﬁce 15 minutes early. What is the usual time taken (in minutes) by me to reach the ofﬁce?

Accepted Answer

Speed and time are inversely proportional. The speed ratio is 7:6, so the time ratio is 6:7. The difference of 1 unit equals 15 minutes. Usual time (7 units) is 7 × 15 = 105 minutes.

Question 13

What is the simpliﬁed value of sec6 A – tan6 A – 3 sec2 A tan2 A?

Accepted Answer

Use the identity sec²A - tan²A = 1. Cubing both sides gives sec⁶A - tan⁶A - 3sec²A tan²A(sec²A - tan²A) = 1. Substituting the identity yields 1.

Question 14

How many shoes are there of Reebok brand?

Accepted Answer

Based on the provided chart or table data, calculate the specific value for Reebok. For example, if Reebok represents 23% of a total 1200 shoes, 0.23 × 1200 = 276.

Question 15

What is the ratio of average number of students studying Arts per year and average number of students studying Science per year?
