Answer 2

Answer:

Step-by-step explanation:

Let the sum lent at 8% is X

and at 10% then sum lent at (10000 - x)

According to the question,

X × 8/100 × 1 + (10000 - X) × 10/100 ×1 = 10000 × 9.2/100 ×1

8X /100 + 10 (10000 -X)/100 = 920

8X /100 + 100000 - 10x/ 100 = 920

8x + 100000 -10X = 92000

-2X + 100000 = 92000

-2x = 92000 - 100000

-2x = - 8000

X = 8000 / 2

X = 4000

sum lent at 8% is X  = 4000

and at 10% then sum lent at (10000 - x) = 10000 - 4000 = 6000
