Question

The approximate ratio of strength of cement concrete at 3 months to that at 28 days of curing is

Answer 1

The ratio is 45:14.

Step-by-step explanation:

Since we have given that

Number of months = 3

Number of days in 3 months is given by

$30\times 3\\\\=90\ days$

Number of given days = 28

We need to find the ratio of strength  of cement at 3 months to at 28 days.

So, the ratio is given by

$90:28\\\\=45:14$

Hence, the ratio is 45:14.
