Step-by-step explanation:
215:474::537::?
Complete Question is with options
a)26
b)27
c)25
d)22
215 = 2 + 1 + 5 = 8
474 = 4 + 7 + 4 = 15 = 1 + 5 = 6
537 = 5 + 3 + 7 = 15 = 1 + 5 = 6
Logic : Next Sum should be 8
26 has 2 + 6 = 8
hence 26 is the answer
Another logic
215 = 2 + 1 + 5 = 8
474 = 4 + 7 + 4 = 15 = 1 + 5 = 6
537 = 5 + 3 + 7 = 15 = 1 + 5 = 6
6 is 2 less than 8
so next number sum should be two less than 6
hence 6 -2 = 4
22 = 2 + 2 = 4
Hence 22 should be answer
