Question

So my question is:-
a) Four friends-Piya,Ishaan,Nihar and Mahek- are stranded in a forest.The only way to safety is through a rickety bridge across a river. It is pitch dark and they have only one torch. No more than two persons can use the bridge at a time. How can all get across in 17 minutes if Piya can cross the bridge in one minute, Ishaan in two minutes, Nihar in five minutes and Mahek in ten minutes?​

Answer 1

Answer:

hey friend this is your answer

We know that PRIYA-1 MIN

ISHAAN-2 MIN , NIHAR -5 MIN AND NIHAR IN 

10 MIN. IF BOTH ISHAAN AND PRIYA CROSS THE BRIDGE IN 2 MINUTES THEN THEY WILL TAKE TOTAL OF 17 MINUTES:-2+5+10=17 MINUTES
