Answer 1

Question:-

• To find the amount if the rate gets increased by 2%.

Answer:-

• 461.92

Solution for Correct answer:

Principal = Rs.400, Amount = Rs.430

Simple Interest = Rs.(430−400)

• −400)=Rs.30

Time = 4 years

Time = 4 yearsRate in percentage =SI×100/P×T

P×TRate in percentage =30×100/400×4

• = 3000/1600
• =1.875 =1.87

New rate of interest

• New rate of interest= (1.87+2) = 3.87%

%Interest= 400×3.87×4/100

• =6192/100
• =61.92

Hence amount = Rs.(400+61.92)

• )=Rs. 461.92
