Answer 2

Answer:

So, 3% will account for Rs. 2300 and Rs. 1700 will account for 5%

Step-by-step explanation:

Total amount of money = Rs. 4000

Let the one part of amount be x then the second part will be (4000 - x)

⇒ 0.03 × x × 1 + (4000 - x) × 0.05 = 144

⇒ 0.03x + 200 - 0.05x = 144

⇒ -0.02x = 144 - 200

⇒ -0.02x = -56

⇒ x = 2300

So, The first part be Rs 2300

Then the second part will be (4000 - 2300) = Rs. 1700

So, 3% will account for Rs. 2300 and Rs. 1700 will account for 5%
