Question:

It is given that x is 15% of y and y is 28% of z. If x = 1050, then find z - y.

Options:

1300

25000

18000

2070

Correct Answer:

18000

Explanation:

x = $\frac{15}{100}$y & y = $\frac{28}{100}$z

x : y = 3 : 20 & y : z = 7 : 25

x : y : z = 21 : 140 : 500

According to question,

21R = 1050

1R = 50

Now, z - y = 500R - 140R = 360R

= 360 × 50

= 18000

The correct answer is Option (3) → 18000
