Q:

405 sweets were distributed equally among children in such a way that the number of sweets received by each child is 20% of the total number of children. How many sweets did each child recieve ?

A) 9	B) 10
C) 11	D) 12

Answer & Explanation Answer: A) 9

Explanation:

Let the total number of children be x.

Then, x * (20% of x) = 405

=> x * 20x/100 = 405

$\frac{1}{5} x^{2}$ = 405

=> x=45

Number of sweets received by each child = 20% of 45 = 9.

A) 10	B) 12
C) 15	D) 18

8x = 20

x = 2.5

Quantity of alcohol = (4 x 2.5) litres = 10 litres.

Q:

56% of 225 + 20% of 150 = ? - 109

Find the value of '?' in the above equation

A) 264	B) 220
C) 241	D) None

Answer & Explanation Answer: A) 264

Explanation:

we know that a% of b = b% of a

Now,

225% of 56 + 20% of 150 = ? - 109

200% of 56 + 25% of 56 + 20% of 150 = ? - 109

112 + 14 + 30 = ? - 109

? = 112 + 14 + 30 + 109

? = 264
