Question

a builder
completed 5/12 of a building in 2 months and 3/7 of the remaining part in the third month 24 feet of the building is still left find the total length of the building​

Answer 1

First, we need to find the total height constructed in 3 months.

5/12 building constructed in 2 months, leaving 7/12 incomplete.

of that; 3/7 was also completed.

hence, total completed = 5/12 + 3/7*7/12

=5/12+3/12

=2/3 completed.

1/3 remaining = 24 ft. (given)

Hence, complete height = 24*3

=72 ft
