Some equations are solved on the basis of a certain system. Find out the correct answer
for the unsolved equation on that basis.
3 + 8 + 5 + 5 = 36,
6 + 2 + 8 + 1 = 16,
8 + 5 + 9 + 5 = 58,
7 + 4 + 3 + 8 = ?
from the given patterns in the first three equations, a general rule can be formulated as:
A+B+C+D= CxD+ A+B. which when applied to
7 + 4 + 3 + 8 = ? will be equal to 3*8+7+4 =35.
hence the correct answer is option A.
