Given volume = 100*.012 = 1.2cum.
Increase mortar by 30% = 1.56cum.
For volume of dry mortar increase 25%= 1.56+ (1.56*.25) = 1.95cum.
Now proportion = 1:6.
k+6k=7k.
So volume of cement = (1/7) * 1.95 = 0.2785.
This is the correct answer.

Total volume = 100*.012 = 1.2cum.
30% more mortar required so 1.2+ (.3*1.20) = 1.56cum.
Now also to get dry volume of mortar, wet wet volume may b further increase by 25%.
So volume of dry mortar = 1.6+ (1.56*.25) = 1.95cum.
Now proportion = 1:6.
So volume of cement = (1/7) * 1.95 = 0.2785 (ans).
