Question
Rs. 8000 was lent in two parts, first part at 5 % p.a.
and the remaining at 4% p.a. If the total simple interest from both the parts in 4 years was Rs. 1360, then what will be the ratio of amount of the 2 different parts?Solution
ATQ, Let first part of money be A rupees then second part will (8000-A) rupees. Simple interest = Principal × Rate of interest × Number of years/100 Now according to question- A×5×4/100 + (8000-A) ×4×4/100 = 1360 20A + 16× (8000-A) = 136000 4A = 136000 – 128000 A = 2000 Second part = 8000-2000 = 6000 Ratio = 2000/6000 = 1:3
