Answer:after 3 years it will become 7986

Answer:

Time = 3 years

Step-by-step explanation:

Amount = ₹7986

Principal = ₹6000

Rate = 10%

Time = n years

Amount = P(1+r/100)ⁿ

₹7986 = ₹6000(1+10/100)ⁿ

7986/6000 = (110/100)ⁿ

1331/1000 = (11/10)ⁿ

(11/10)³ = (11/10)ⁿ

Bases are same, Power will also be same

3=n

Time = 3 years
