After spending 40 % in machinery, 25 % in the building, 15 % in raw material and 5 % on furniture, Haris had a balance of Rs. 1305. The money with him was:________?

A. Rs. 6500
B. Rs. 7225
C. Rs. 8700
D. Rs. 1390
Explanation:
x – [40 % of x + 25 % of x + 15 % of x + 5 % of x] = 1305
or x – 85 % of x = 1305
or 15 % of x = 1305 x 130500/15 × 8700
= Rs. 8700

A man donated 5 % of his income to a charitable organization and deposited 20 % of the remainder in a bank. If he now has Rs. 1919 left, what is his income?

A. Rs. 2558. 60
B. Rs. 2525
C. Rs. 2500
D. Rs. 2300
Let his income be Rs. x.
Then X – 5 % of x – 20 % of 95 % of x = 1919
or x – x/20 – (20×95×x)/(100 × 100) = 1919
or x – x/20 – 19x/100 = 1919
or 100x – 5x – 19x = 191900
X = 191900/76= 2525

Raees credits 15 % of his salary in this fixed deposit account and spends 30 % of the remaining amount on groceries if the cash in hand is Rs. 2380, what is his salary?

A. Rs. 3500
B. Rs. 4000
C. Rs. 4500
D. Rs. 5000
Let salary be Rs. x.
Then, x – 15 % of x – 30 % of 85 % of x = 2380
or x – 15x/100 – (30×85×x)/(100×100) = 2380
or 200 x – 30 x – 51 x = 2380 X 200
or 119 x = 2380 X 200
or x = (2380×200)/119 = 4000

The income of a broker remains uncharged though the rate of commission is increased from 4 % to 5 % the percentage of a slump in business is_______?

A. 8 %
B. 1 %
C. 20 %
D. 80 %
Explanation:
Let the business value changes from x to y.
Then 4 % of x = 5 % of y of 4/100 × x = 5/100 × y
or y = 4/5 x.
Change in business = (x – 4/5 x) = 4/5 x.
Percentage slump in business
= (1/5 x ×1/x × 100)% = 20%

The Price of an article is cut by 10%. To restore it to the former value, the new price must be increased by_______?

D. 11%
Let original price = Rs. 100
Then new price = Rs. 90
Increase on Rs. 90 = Rs. 10
Increase % = [10/90 X 100] % = 11 1/9 %

What percentage of numbers from 1 to 70 have squares that end in the digit 1?
