If she paid 10250 rupees as total interest .
How much money did she borrowed from bank ​

Answer 1

Answer:

She borrowed from bank ​41000 rupees.

Step-by-step explanation:

given rate r = 10 p.c.p.a

time t = 2 and half year = 2 and 1/2 = 5/2 year

interest = 10250

we know formula of simple interest

simple interest = (P×r×t)/100

put given values

10250 = (P×10×5/2)/100

solving this

10250 = P/4

P = 41000

capital money P = 41000 rupees

Answer 2

let,

rate =10%= 1\10

1000x

/ | \

100x 100x 50x

total interest on 1000 at 10% in 2.5year is 250

therefore 250x = 10250

x = 10250/250

x = 41

therfore 1000x = 1000×41
