Question

If 8 men and 12 boys can finish a work in 10 days and if 6 men and 8 boys can finish a work in 14 days

Answer 1

yes, because you can see that 8 men -10 day =2 day,

if 10 days- 12 boy=2day

so, the answer is obviously right.

Answer 2

Answer:

4 days

Step-by-step explanation:

26M + 48B -> 2days] => TOTAL WORK = 52MD + 96BD

So,  60MD+80BD=52MD+96BD  

=>8MD=16BD  

=>1 MD = 2 BD  

Or, we can say 1 man is equivalent to 2 boys.

Thus, TOTAL WORK = 60 MD + 80 BD = 60 MD + 40 MD = 100 MD

Now, 15M + 20B = 15M + 10M = 25M

So, time taken =  100MD25MD  = 4 days (Answer)
