What sur​

Answer 1

Answer :-

Given :-

• Amount = Rs. 12000
• Rate of interest = 3% p.a.
• Time = 6 years

To Find :-

• Sum / Principal

Solution :-

Let the sum be x

→ Simple interest = Amount - sum

→ Simple interest = 12000 - x

Substituting the value in formula :-

→ SI = P × R × T / 100

→ 12000 - x = x × 3 × 6 / 100

→ 12000 - x = 18x / 100

→ 100 ( 12000 - x ) = 18x

→ 1200000 - 100x = 18x

→ 118x = 1200000

→ x ≈ 10169.5

Sum = Rs. 10169.5
