Question

A earns25/2 % more than B.I they jointly earns Rs.35700 a year then amount A earns annually is?​

Answer 1

$\huge\pink{Solution}$

Let B earns Rs. X.

So, Earning of A =

$x + \frac{25}{200} x = \frac{225}{200} x = \frac{9}{8} x$

Jointly Earning =

$x + \frac{9}{8} x = \frac{17}{8} x$

According to question,

$\frac{17}{8} x = 35700 \\ x = \frac{35700 \times 8}{17} \\ x = 2100 \times 8 \\ x = 16800$

So, Earning of B = Rs. 16800

& Earning of A =

$\frac{9 \times 16800}{8} = 9 \times 2100 = rs.18900$
