Question

14% of $250\times ?\%$ of 150 = 840

• A. 15
• B. 18
• C. 16
• D. 12
• E. None of these

Answer 1

The correct option is C 16

Here, 14% of $250\times ?\%of150=840$
It can also be simplified as
$\Rightarrow \frac{14}{100}\times 250\times x\%of150=840$
[taking x at the place of ?]
$\Rightarrow \frac{14}{100}\times 250\times \frac{x}{100}\times 150=840$
$\Rightarrow \frac{3500}{100}\times \frac{x}{100}\times 150=840$
$\Rightarrow x=\frac{840\times 100}{150\times 35}=\frac{24\times 100}{150}=16$
