Question

1) Divide rs 6000 into 2 parts so that the S. I on the 1st part for 9 months at 12% per annum is equal to the S. I on the 2nd part for 3/2 years at 10% p. a

​

Answer 1

Answer: Rs 3750 & Rs 2250

Step-by-step explanation:

Let, First part be Rs x

Then second part = Rs(6000 - x)

S.I = PRT

A/Q

=> x * 12/100 * 3/4  =  (6000 - x) 1.5 * 10/100

=> 9/100 * x = (6000 - x) 15/100

=> 9x = 90000 - 15x

=> 24x = 90000

=> x = 3750

∴ First part = Rs 3750

and second part = Rs(6000 - 3750) = Rs2250
