Q 2 - The sum of two numbers is 2490. If 6.5% of one number is equal to 8.5% of the other, then the numbers are?
Answer : A
Explanation
Let p and q be the numbers. Then, 6.5% of p = 8.5% of q p = 85⁄65q i.e p = 17⁄13q Now, p + q = 2490 i.e. 17⁄13q + q = 2490 Therefore, q = 1079 This shows the two numbers are : q = 1079 and 17⁄13q = 1411 = p
Q 3 - The population of a town increased from 175000 to 262500 in a decade. The average percent increase of population per year is:
Answer : C

Increase in 10 years = (262500 - 175000) = 87500 Increase % = (87500⁄175000) = 50% Therefore, average = (50⁄10)% = 5%
Q 4 - Two tailors Rajiv and Raman are paid a total of Rs. 550 per week by their employer. If Rajiv is paid 120% of the sum paid to Raman, then how much is Raman paid per week?

Q 5 - A sum of Rs 817 is divided among A, B and C such that A receives 25% more than B and B receives 25% less than C. What is the A share in the amount?
Answer : C

Q 8 - On decreasing the price of refrigerator by 25%, its sale is increased by 20% .what is the effect on revenue received by the shopkeeper?

Answer : D
Explanation
Let, the total number of candidates = x Hence, number of candidates passed in English = 0.6x Similarly, number of candidates passed in Mathematics = 0.7x Number of candidates failed in both the subjects = 0.2x Number of candidates passed in at least one of the subjects =x-0.2x = 0.8x ∴ 0.6x+0.7x-2500=0.8x Or,1.3x0.8x=2500 Or,0.5x=2500 Or,x=5000
