If P : Q : = 8 : 15 and Q : R = 3 : 2, then find P : Q : R
Given that, P : Q = 8 : 15, Q : R = 3 : 2
P : Q : R = (8 x 3) : (15 x 3) : (15 x 2) = 24 : 45 : 30
∴ P : Q : R = 8 : 15 : 10

A bag contains one rupee, 50 paise 25 paisa coins in the Ratio of 8:9:11. If the total money in the bag is Rs. 366, find the number of 25 paisa coins.
Let coins are
1 ruppe coin = 8X.
Value of 1 ruppe coin = 8X.
50 paise coins = 9X
Value of 50 paise coin = 9X/2
25 paise coins = 11X
Value of 25 paise coins = 11X/4.
Total Ruppes = 366
8X + 9X/2 + 11X/4 = 366
61X/4 = 366
61X = 1464
X = 24.
Number of 25p paise coin = 11X = 11* 24 = 264.
