Pinku, Rinku and Tinku divide an amount of ₹ 4200 amongst themselves in the ratio of 7 : 8 : 6, respectively. If an amount of ₹ 200 is added to each of their shares, what will be the new respective ratio of their shares of amount ?
-
- 8 : 9 : 5
- 7 : 9 : 5
- 7 : 8 : 6
- 8 : 9 : 7
Correct Option: D
Let pinku's share = 7N
Rinku's share = 8N
Tinku's share = 6N
According to the question,
7N + 8N + 6N = 4200
⇒ 21N = 4200
∴ N = 4200/21 = 200
Hence. amount of Pinku = 7N = 7 x 200 = ₹ 1400
Amount of Rinku = 8N = 8 x 200 = ₹ 1600
Amount of Tinku = 6N = 6 x 200 = ₹ 1200
Now. ₹ 200 is added to each share
Then,
New ratio of shares
= (1400 + 200) : (1600 + 200) : (1200 + 200)
= 1600 : 1800 : 1400
= 16 : 18 : 14 = 8 : 9 : 7
