Answer 1

Answer

Open in answr app

suppose x and y are two divided

parts of 4500. then

x+y=4500 __ (1)

given

5% of x = 10% of y

1005x=10010y

x=2y

2y+y=4500

3y=4500

y=1500

x+1500=4500

x=4500−1500

x=3000

hence the 4500 is been divided into 

two parts of 1500 and 3000.

Answer 2

Step-by-step explanation:

Let the part given at 5% be P and the part given at 6% be p

So P + p = 2500 —————————(i)

Simple interest = ( principle x rate x time) /100

So

(P x 5 x 1)/100 +(p x 6 x 1)/100 = 140

5P + 6p = 14000 —————————(ii)

On solving equation (i) and (ii) we get

P= Rs 1000 &

p= Rs 1500

Therefore Rs 1000 was lent at 5 % and

Rs 1500 was lent at 6%
