(b)The steps on which the cat jumps:
The correct option is B 12th To find the first common landing step of the cat and frog we need to find the least common multiple of the 4 and 3 multiples of 3 = 3 x 1 = 3 3 x 2 = 6 3 x 3 = 9 3 x 4 = 12 3 x 5 = 15 3 x 6 = 18 3 x 7 = 21 3 x 8 = 24 3 x 9 =27 3 x 10 = 30 Multiples of 4 = 4 x 1 = 4 4 x 2 = 8 4 x 3 = 12 4 x 4 = 16 4 x 5 = 20 4 x 6 = 24 4 x 7 = 28 4 x 8 = 32 4 x 9 =36 4 x 10 = 40 So LCM of 3 and 4 is 12
