Question

Three dispensaries received mosquito nets as follows: one got a fifth of the nets while the second one got a 1/3 of the nets, the third one got half of what REMAINED. If the distributor remained with 1260 mosquito nets, how many mosquito nets were there altogether ?

Answer 1

5400

Explanation:

1/5 +1/3=8/15

15/15-8/15=7/15

third got 1/2of 7/15=7/30

7/30+8/15=23/30

30/30-23/30=7/30

if 7-1260

30- ?

( 30×1260÷7)=5400
