Answer 2

Given :-

• Principal = Rs 4000
• Rate = 2%
• Simple Interest = Rs 400

To Find :-

• Time

Solution :-

❏ As we know that, Simple Interest is given by [ Simple Interest = P × R × T / 100 ] where P , R and T stands for Principal , Rate and Time respectively.

Putting the Values :

⟾⠀⠀Simple Interest = P × R × T / 100

⟾⠀⠀400 = 4000 × 2 × T / 100

⟾⠀⠀400 = 40 × 2 × Time

⟾⠀⠀400 = 80 × Time

⟾⠀⠀400 / 80 = Time

⟾⠀⠀40 / 8 = Time

⟾⠀⠀5 years = Time

________________

Verification :

➞ Simple Interest = P × R × T / 100

➞ Simple Interest = 4000 × 2 × 5 / 100

➞ Simple Interest = 40 × 2 × 5

➞ Simple Interest = 40 × 10

➞ 4000 = 4000

Hence Verified

Thus, Time = 5years
