Option (b) is correct

Let the principal be Rs. x

SI = (p*r*t)/100 (SI = A – P)

So, (1512 – x) = (x*5*4)/100

x = 7560/6 = 1260 (Principal)

Now same principal at 10% P.A in 25 years.

SI = (1260*10*2.5)/100

SI = 315

Hence A = 1260 + 315 = 1575

विकल्प (b) सही है

मूलधन 100 रुपये मान लेने पर

SI = (p × r × t)/100

(SI = A – P)

इसलिए, (1512 – x) = (x × 5 × 4)/100

x = 7560/6 = 1260 (मूलधन)

अब 25 वर्षों में 10% प्रति वर्ष पर मूलधन

SI = (1260 × 10 × 2.5)/100

SI = 315

अतः A = 1260 + 315 = 1575
