Its a simple unitary method problem…
6 men will do the work in 12 days
1 man will do in 6*12 = 72 days
So, 5 men will do it in 72/5 = 14.4 days
There are two types of relation
<span>Direct relation - If one quantity increases then the other also increases and if one quantity decreases then the other also decreases.</span>
Example- If 3 pencils cost Rs 7, then what will be the cost of 5 pencils ?
3 pencils cost Rs 7
1 pencil will cost Rs 7/3 (First divide)
5 pencils will cost Rs (7/3)*5 = Rs 11.66 (Then Multiply)
<span><span>Inverse relation : </span>If one quantity increases then the other decreases and if one quantity decreases then the other increases.</span>
Example - This question itself is the example of inverse relation. Here first we did multiplication and then division.
I hope it clears the image….
