Question

Find the principal when S.I =Rs 648, time = 6 years and rate=12%​

Answer 1

Given :-

• Simple Interest (S.I) = Rs,648
• Rate (R) = 12%
• Time (T) = 6years

To Find :-

• Principal

Solution :-

We know that, Simple Interest is given by Simple Interest = Principal × Rate × Time/100

Putting the Values :

➞ Simple Interest = P × R × T / 100

➞ 648 = Principal × 12 × 6 / 100

➞ 648 = Principal × 72 / 100

➞ 648 × 100 / 72 = Principal

➞ 64800 / 72 = Principal

➞ 900= Principal

________________

Verification :-

➞ Simple Interest = P × R × T / 100

➞ Simple Interest = 900 × 12 × 6 / 100

➞ Simple Interest = 9 × 12 × 6

➞ Simple Interest = 9 × 72

➞ 648 = 648

________________

Therefore, Principal = Rs,648
