(B) Let the required sum of money be $₹ x$.Simple Interest $(SI)$ is calculated using the formula: $SI = \frac{P 	imes R 	imes T}{100}$.According to the problem,the simple interest on $₹ x$ for $4$ years at $5 \%$ $p.a.$ is equal to the simple interest on $₹ 560$ for $10$ years at $4 \%$ $p.a$.So,$\frac{x 	imes 5 	imes 4}{100} = \frac{560 	imes 4 	imes 10}{100}$.Canceling $100$ from both sides,we get: $x 	imes 20 = 560 	imes 40$.$x 	imes 20 = 22400$.$x = \frac{22400}{20} = 1120$.Therefore,the sum of money is $₹ 1120$.

If simple interest on a certain sum of money for $4$ years at $5 \%$ $p.a.$ is same as the simple interest on ₹ $560$ for $10$ years at the rate of $4 \%$ $p.a.$,then the sum of money (in ₹) is
