hey have to pump 150 balloons and
the party will start in 3 hours,
To Find : will they be able to make if they work together
Solution:
1 hr = 60 mins
3 hrs = 180 mins
Xyra can pump 10 balloons in 35 mins
=> Balloons pumped in 35 mins = 10
=> Balloons pumped in 1 mins = 10/35
=> Balloons pumped in 180 mins = 180 * 10 / 35
= 51.4
Hence 51 Balloons can be pumped by Xyra in 3 hrs
Luisa can pump 15 balloons in 32 mins
=> Balloons pumped in 32 mins = 15
=> Balloons pumped in 1 mins = 15/32
=> Balloons pumped in 180 mins = 180 * 15 / 32
= 84.375
Hence 84 Balloons can be pumped by Luisa in 3 hrs
Bot Together can pump = 51 + 84 = 135 Balloons
135 < 150
Hence They will not be able to make it
