Question

Given that a, b and c are three consecutive multiples of 5. Choose the correct option.

• A. a + b + c = 15
• B. b = a + 5
• C. c = b + 5
• D. a = c - 10

Answer 1

Answer: (B), (C), (D)

The correct options are
B

b = a + 5

C

c = b + 5

D

a = c - 10

The consecutive multiples of '5' differ by 5.

Here the first multiple is 'a'
So, b = a + 5
And , c = b + 5
Now, c = a + 5 + 5 (putting b = a + 5 )
c = a + 10
or, a = c - 10
