Question
A person invested Rs. ‘x’ in account A and Rs.
‘x/2’ in account B. Account A gives 4% simple interest per annum while account B gives 7%. After 5 years, the total interest received is Rs. 825. What is the value of ‘x’?Solution
ATQ,
x × 0.04 × 5 + x/2 × 0.07 × 5 = 825
0.2x + 0.175x = 825
0.375x = 825
x = 825 / 0.375 = 2200
So, the value of ‘x’ is Rs. 2200
