Question
A businessman took a loan at 25% p.a. simple interest.
After 40 months, he repaid Rs. 12,500 to clear the loan. Find the principal amount borrowed.Solution
ATQ,
Let the borrowed amount be Rs βxβ.
ATQ;
(12500 β x) = (x Γ 25 Γ 40) Γ· (100 Γ 12)
Or, (12500 β x) = (25x/30)
Or, 12500 = {(25x/30) + x}
Or, 12500 = (55x/30)
So, x = 6818
Therefore, the borrowed amount was Rs. 6,818.
