Q 4 - Suresh spends 24% of his monthly income on food and 15% on the education of his children. Of the remaining salary, he spends 25% on entertainment and 20% on conveyance. He is now left with Rs. 10736. What is the monthly salary of Suresh?

Answer : A

Explanation

Let z be the monthly salary of Sameer.
[100-(25 + 20)]% of [100 - (24 + 15)]% of x = 10736

Rs. 32000

Q 5 - Of the 1000 inhabitants of a town, 60% are males of whom 20% are literate. If, of all the inhabitants, 25% are literate, then what percent of the females of the town are literate?

Answer : D

Explanation

⁶⁰⁄₁₀₀ x 1000 = 600 = number of males
→ 1000 - 600 = 400 = number of females
Literates = 25% of 1000 = 250
Literate males = 20% of 600 = 120
Literate females = 250 - 120 = 130
Therefore, the percent of the females literate = ¹³⁰⁄₄₀₀ x 100 = 32.5%

Q 6 - The price of a certain item is increased by 15%. If a consumer wants to keep his expenditure on the item the same as before, how much percent must he reduce his consumption of that item.

If the price of a commodity increases by R%, to maintain the same expenditure, the reduction in consumption can be represented by:
{R/(100 + R)}*100%
 = {15/(100 + 15)} * 100
 = 300/23%

Q 7 - The income of broker remains unchanged though the rate of commission is increased from 5% to 6% .the percentage of slump in business is

Answer : B

Explanation

Let the business value changes from x to y
Then, 5% of x=6% of y or 5/100*x=6/100 y
Or y = 5/6x
Change in business = x-5/6x=1/6x
 Percentage slum in business=1/6 x * 1/x*100=100/6 %

Q 8 - The price of an article is cut by 20% .to restore it to the former value, the new price must be increased by

Q 10 - The production of company A increased by 25% from 1994 to 1995 and its production further increased by 60% from 1995 to 1996. What is the total percent increase in production from 1994 to 1996?

Answer : D

Explanation

Production in 1996 = 160/100 * 125/100 * Production on 1994
= 20000/10000 * Production on 1994
= 2 * Production on 1994
∴ Required % Increase = {(Production on 1996 - Production on 1994)/ Production on 1994}*100%
Consider, Production on 1994 = x. Then, Production on 1996 = 2x.
= (2x � x)/x * 100%= 100%
