Question

1. Find the Principal when…..

(a) S.I. = $ 192 Rate = 6% per annum Time = 4 years

Answer 1

Answer:

P= R×T/100×SI...............

Answer 2

Given :-

S.I. = $ 192 Rate = 6% per annum Time = 4 years

To find :-

Principal

Solution :-

• Simple Interest = $192

• Rate of interest = 6%

• Time = 4 years

As we know that

→ Simple interest = Principal × rate × time/100

→ S.I = P × R × T/100

→ 192 = P × 6 × 4/100

→ 192 = 24P/100

→ 19200 = 24P

→ P = 19200/24

→ P = 800

Hence,

• Principal is Rs.800

More to know :-

• Amount = Simple interest + Principal
• Compound interest = Amount - Principal
