Answer»

Let M be the sum of money.

Simple interest, SI = P × R × T/100

where

P = principal amount

R = rate of interest and

T = time.

? TOTAL interest = Rs. 624

$(\Rightarrow \frac{{\frac{{2M}}{3} \times 6 \times 6}}{{100}} + \frac{{\frac{M}{3} \times 4 \times 6}}{{100}} = 624 \Rightarrow M = 1950)$
