John and Ismail donated some money to the Relief Fund. The amount paid

1.	John and Ismail donated some money to the Relief Fund. The amount paid by Ismail is ₹85 more than twice that of John. If the total money paid by them is ₹4000, then find the amount of money donated by John.
Answer» Let the amount donated by John = ₹x The amount donated by Ismail is ₹85 more than twice of John. So, the amount donated by Ismail = ₹(2x + 85) Total amount = John amount + Ismail amount = ₹4000 ⇒ x + 2x + 85 = 4000 ⇒ 3x + 85 = 4000 ⇒ 3x + 85 – 85 = 4000 – 85 (Subtract 85 on both sides) ⇒ 3x = 3915 ⇒ 3x/3 = 3915/3 (Divide by 3 on both sides) ⇒ x = 1305 ∴ Money donated by John = x = ₹ 1305 ∴ Money donated by Ismail = 2x + 85 = 2(1305) + 85 = ₹2695

Answer»

Let the amount donated by John = ₹x

The amount donated by Ismail is ₹85 more than twice of John.

So, the amount donated by Ismail = ₹(2x + 85)

Total amount = John amount + Ismail amount = ₹4000

⇒ x + 2x + 85 = 4000

⇒ 3x + 85 = 4000

⇒ 3x + 85 – 85 = 4000 – 85 (Subtract 85 on both sides)

⇒ 3x = 3915

⇒ 3x/3 = 3915/3 (Divide by 3 on both sides)

⇒ x = 1305

∴ Money donated by John = x = ₹ 1305

∴ Money donated by Ismail = 2x + 85

= 2(1305) + 85

= ₹2695
