Interest earned when a sum of Rs. 1,200/­ was invested for 4 years in scheme A at 20% S.I. = $$frac{1,200 imes 20 imes 4}{100}$$ = $$12 imes 80 = 960$$ Amount received when Rs. x was invested for 2 years in scheme B at 10% C.I. = $$x (1 + frac{10}{100})^2$$ = $$x (frac{11}{10})^2 = frac{121x}{100}$$ Acc to ques, => $$frac{121x}{100} - 960 = 1460$$ => $$frac{121x}{100} = 1460 + 960 = 2420$$ => $$x = frac{2420 imes 100}{121}$$ => $$x = 20 imes 100$$ = Rs. $$2,000$$
