Lalita borrowed some money from her friend at 6% per annum. If she paid ₹313.50 as simple interest after 2 years and 9 months, what is the sum that Lalita borrowed?
​

Answer 1

Answer:

₹ 1900

we can find it by the formula p×t×r/100

hence p=x

t=2 years 9 months I. e2 3/4years

r is given =6%

after two years the S.I is ₹313.5

let's solve

313.5= p×t×r/100

313.5=x×2 3/4×6/100

31350=x×2 3/4× 6

31350×4/11×1/6=1900

x=₹1900
