M150 grade is not a nominal mix, it's a design mix which is batched by weight so the answer would be E.
(1)

I think the question is wrong. Because M150 grade concrete has no nominal mix. It is in design mix.

M 5=1:5:10
M 7.5=1:4:8
M 10=1:3:6
M 15=1:2:4

M 20=1:1.5:3
M 25=1:1:2.

As per IS 456-2000 code.

This is the wrong answer. The correct answer will be 1:2:4. 1:1:2 is the proportion of M25.

M 5 -> 1:5:10

M 7.5 -> 1:4:8

M 10 -> 1:3:6

M 15 -> 1:2:4

M 20 -> 1:1.5:3

M 25 -> 1:1:2

This is wrong answer correct as IS 456 is M 15-1:2:4.

Please make the correction.

M5 = 1:6:12.
M7.5 = 1:4:8.
M10 = 1:3:6.
M15 = 1:2:4.
M20 = 1:1.5:3.
M25 = 1:1:2.

Answer is 1:2:4 WHICH IS THE Ratio of M15 Grade of concrete i.e Answer is (C).

RanoDip said:   6 years ago
M10= 1:3:6.
M15= 1:2:4.
M20= 1:1.5:3.
M25= 1:1:2.
So, the answer is option C.
