Question

14%of250*?%150=840 solve this question ​

Answer 1

The value of a is 16

Solution:

14% of 250 x ?% 150 = 840

Let the unknown be a

Therefore,

$14 \% \text{ of 250 } \times a \% \times 150 = 840$

We know that,

$\boxed{a \% \text{ of b } = \frac{a}{100} \times b}$

Therefore,

$\frac{14}{100} \times 250 \times \frac{a}{100} \times 150 = 840\\\\0.14 \times 250 \times 0.01a \times 150 = 840\\\\52.5a = 840\\\\a = \frac{840}{52.5}\\\\a = 16$

Thus a is 16
