Question

8. ? % of 225 + 22% of 555 = 203.1
(a) 23 (b) 44 (C) 36(d) 58(e) None of these​

Answer 1

The answer is (d)36.

• Given condition is x% of 225 + 22% of 555 = 203.1
• We write the given condition in the equation form as:

x% of 225 will be written as:

$\frac{x}{100}$ × 225

22% of 555 will be written as:

$\frac{22}{100}$ × 555

• Now the sum is given as 203.1

$\frac{x}{100}$ × 225 + $\frac{22}{100}$ × 555 =203.1

$\frac{x}{100}$ × 225 + $\frac{1221}{10}$ = 203.1

$\frac{x}{100}$ × 225 = $\frac{2031}{10}$ - $\frac{1221}{10}$

$\frac{x}{100}$ × 225 = $\frac{810}{10}$

$\frac{x}{100}$ = $\frac{81}{225}$

x = $\frac{81}{225}$ × 100

x = 36
