The ratio of basketball to soccer ball => 7:3


Target question => What is the total number of basketballs and soccer balls in the gym?
Let number of basketballs = 7x and soccer balls = 3x


Statement 1 => The difference between the number of basketballs and soccer balls in the gym is 24
7x - 3x = 24
4x/4 = 24/4
x = 6
Basketballs = 7x = 7 * 6 = 42
Soccer balls = 3x = 3 * 6 = 18; total = 42 + 18 = 60
Statement 1 is SUFFICIENT

Statement 2 => The number of basketballs in the gym is between 36 and 55
Total basketballs is supposed to be a multiple of 7 (7x) but there are 2 different multiples of 7 between 36 and 55, so the answer is not definite and statement 2 is NOT SUFFICIENT

Since only statement 1 is SUFFICIENT,
Answer = A
