Question

Q) Amita invested some part of 35000 at 4% and the rest at 5% interest for 1 year. altogether her again was 1530. Find out the amount she had invested at the two different rates.

x+y = 35000 ...(I)

4/100 x + 5/100 y = 1530 ...(II)

How to find x & y ?

Answer 1

Answer:

x = 22000,

x = 22000,y = 13000

Step-by-step explanation:

Given x + y = 35000 --(1)

$\frac{4x}{100}+\frac{5y}{100}=1530$

/* Multiply each term by 100, we get

$\implies 4x+5y = 153000\:--(2)$

/* Multiply equation (1) and subtract from equation (2), we get

4x+5y = 153000

4x+4y = 140000

__________________

*** y = 13000

___________________

Substitute y value in equation (1) ,we get

x + 13000 = 35000

=> x = 35000-13000

=> x = 22000

Therefore,

x = 22000,

y = 13000
