Question

The number that is obtained after increasing 70 by 30 $\%$ is:

• A. 91
• B. 98
• C. 111
• D. 70$\%$ of 150

Answer 1

The correct option is A 91

We can either express the given quantity in terms of fraction or percentage.

$\frac{30}{100}\times 70=21$

$\therefore$ The number obtained after a 30 $\%$ increase is 70 + 21 = 91

Alternate method:

Increased value = 70 x 1.3 = 91.0
