Total no. Of families who take newspaper =80
1>>%age of family takes HINDU=60%
ie...60/100×80=48
2>>>%age of family takes REGIONAL=80%
ie..80/100×80=64
3>>>%age of family takes TOI=70%
ie...70/100×80=56
Now...
To find the common families out of these detaILS provided we simply take out H.C.F of thee result we got
Ie HCF of 48,64,56...=2x2x2=8
Therefore...80/8×100=10% of family takes all the three..
