In a game of pool, the solids to stripes balls ratio were 7 : 2. Had the number of stripes been 27 more, then the solids to stripes ratio would have been 11 : 7. The total number of solids and stripes in the game of pool was?
Answer & explanation
Correct answer: option 2
Solid : Stripes
7 : 2 ............(i)
11 : 7 ............(ii)
In both conditions the number of solid balls is same.
Therefore, to make the ratio of solid balls equal, (i) × 11 & (ii) × 7, we get,
Solid : Stripes
77 : 22 ⇒ 99 (total)
77 : 49
Difference of stripes = 49R - 22R = 27R
ATQ,
27R = 27 (given)
Hence, Total number of balls = 99R = 99
