Raman, Ram, Ramu and Ramana bought a certain number of apples. Ramana bought half the number of apples bought by the other three. Ramu bought one-third the number of apples bought by the other three, while Raman bought two-fifths the number of apples bought by the other three. If each of them bought a distinct number of apples, find the ratio of the number of apples bought by Ram to the total number of apples bought by all four.
Ritu was asked to multiply a two-digit number N by a three-digit number M. But she mistakenly multiplied N by the number formed by writing the digits of M in the reverse order, thereby getting an answer which was 22770 more than the correct answer.
1) Find the correct product of N and M, if it is known that had Ritu reversed the digits of both the numbers N and M, she would have got an answer 12816 more than her earlier answer.
A. 9982 B. 13284 C. 32752 D. 45568 E. 13842
2) What is the minimum possible sum of the digits of M?
A. 8 B. 11 C. 6 D. 5 E. 7
