The number of positive multiples of 49 less than 2000 can be computed as 1960, the highest multiple, minus 49, the lowest, divided by 49, plus 1. In formulas \(\frac{(1960-49)}{49}+1 =
40\). The same rationale works for multiples of 50 less or equal than 2000, i.e. \(\frac{(2000-50)}{50}+1 = 40\).

Keep things simple when working with multiples -
if you divide 2000 by 49 the result is 40.xxx. Because the last multiple of 49 is to be less than 2000 the result is 40 for A

for B, follow the same 2000/50 = 40 exact. The question says less than equal to for B. Hence the value for B is also 40.
So, A = 40, B = 40.......ans- C
