Question

Eight boxes each hold the same number of machine parts. Only one
answer below shows the total number of parts. Which is it?
(a) 135 (b) 138 (c) 136
(d) 133​

Answer 1

Answer:

(c) 136

Step-by-step explanation:

Let no. of machine parts in one box = x

Then no. of machine parts in eight boxes = 8x

⇒Now, if 8x = 135

x = 135/8

Which is not a whole number

⇒Now, if 8x = 138

x = 138/8

Which is not a whole number

⇒Now, if 8x = 136

x = 17

Which is a whole number

Therefore, Correct answer is (c) 136
