Question

Divide ₹3000 into two part such that simple interest on the first part for 4 year is 8% per annum is equal to the simple interest on the second part for 2 year at 9% per annum​

Answer 1

Step-by-step explanation:

money=3000rs

let the first part be x

and second part be3000-x

according to the question,

s.i for first part

t=4yrs

R=8%

s.i for second part

t=2yrs

R=9%

so,

s.i= p*r*t/100

x*4*8/100=(3000-x)*9*2/100

32x/100=18(3000-x)/100

3200x=1800(3000-x)

3200x=5400000-1800x

5000x=540000

x=1080

the first part is=x=1080

second part=3000-x

3000-1080
