Dheeraj had 23000.he invested some amount in scheme A at SI at 20%and the remaining amount in scheme B at CI at 10%. If sanjay got the same amount from both of them at the end of one year how much did he invest in scheme B?
Answers
Solution :-
Let us assume that, dheeraj invested Rs.x in scheme B .
so,
→ Principal in scheme A = Rs.(23000 - x)
→ Rate = 20% per annum .
→ Time = 1 year .
then,
→ Amount = P + SI = (23000 - x) + {(23000 - x) * 20 * 1}/100 = Rs. (6/5)(23000 - x)
now,
→ Principal in scheme B = Rs. x
→ Rate = 10% per annum
→ Time = 1 year .
then,
→ Amount = P[1 + (R/100)]^T = x * [1 + (10/100)]¹ = Rs. (11x/10)
A/q,
→ (6/5)(23000 - x) = (11x/10)
→ 12 * 23000 - 12x = 11x
→ 12x + 11x = 12 * 23000
→ 23x = 12 * 23000
→ x = 12 * 1000
→ x = Rs.12000 (Ans.)
Hence, Dheeraj invested Rs.12000 in scheme B .
