A bag contains 50 paisa, 25 paisa and 10 paisa coins in the ratio of 7 : 4 : 3. If the total amount in the bag is Rs.144, then find the number of 10 paise coins.
Answer & explanation
Correct answer: option 2
50 P. 25 P. 10 P.
No. of Coins ⇒ 7 : 4 : 3
Value ⇒ 3.5 : 1 : .3 ⇒ 4.8R
4.8R = 144 (given)
1R = 30
No. of 10 P. coins = 3R = 3 × 30 = 90
