Mathematics Question on Simple Interest
Vibhuti bought a car worth ₹10,25,000 and made a down payment of ₹4,00,000. The balance is to be paid in 3 years by equal monthly installments at an interest rate of 12% p.a. The EMI that Vibhuti has to pay for the car is:
(Use (1.01)−36=0.7)
₹20,700.85
₹27,058.87
₹25,708.89
₹20,833.33
₹20,833.33
Solution
The formula for EMI is:
EMI=P⋅(1+r)n−1r(1+r)n,
where:
P: Loan amount =6,25,000,
r: Monthly interest rate =1212%=1%=0.01,
n: Loan tenure in months =36.
Substituting the values:
EMI=6,25,000⋅(1+0.01)36−10.01(1+0.01)36.
Given:
(1.01)−36=0.7⟹(1.01)36=0.71=1.4286.
Simplify:
EMI=6,25,000⋅1.4286−10.01⋅1.4286.
Numerator:
0.01⋅1.4286=0.014286.
Denominator:
1.4286−1=0.4286.
Simplify the fraction:
0.42860.014286≈0.03333.
Thus:
EMI=6,25,000⋅0.03333=20,833.33.
Final Answer:
20,833.33
