Answer: (e)

240% of 700

= 700 × $24\/0/100$ = 1680

Answer: (c)

Let original salary of a person = x Rs.

Increase in salary = 10% of x

Then New Salary = x + 10% of x

$x + 10/100 × x = 11/10x$

But he received same amount even after increment.

Let y be the percentage salary he did not receive. then

$11/10x - 11/10x × y/100 = x$

$11/10x[1 - y/100] = x$

$1 - y/100 = 10/11$

$y/100 = 1 - 10/11 = 1/11$

$y = 100/11%$

∴ Option (c) is correct.
