Ans 1: (Master Answer)
(B): A. 40 thousands + 20 tens + 90 ones = 40000 + 200 +90 = 40290 (Incorrect)
B. X = 10 and L = 50. And we can do 50 - 10 = 40. (Incorrect)
C Third multiple of 8 = 8 × 3 = 24.
Fifth multiple of 5 = 5 × 5 = 25
So, 24+25 = 49 (Correct)
D. 8 × 4 = 32, 8 × 7 = 56. Hence, 8 is a factor of 32 and 56. (Correct)
