Arithmetic : Level 2 Test-6
Now second bottle does not contain any alcohol so the required quantity will be 1/3 x 1/5 = 1/15
which is half the time it takes Puran to reach Mohan's house.
Therefore it is simple that Mohan will be on the half way in 12.5 minutes and Puran can reach to the half way in 25 minutes,
so the time required for Puran to reach in the middle is 25- 12.5 = 12.5 mins.
2 h and 12 min
1 hour and 30 min
3 h and 15 min
Car B is travelling at 15% slower than the A therefore the speed of the car B = 102km/h
Distance travelled by the car in one and half hour = 180 km
Distance remaining between both now = (668.4 – 180) km
Now relative speed will be (120 + 102) km/h
And therefore the required time will be (668.4 – 180) km/h / (120 + 102) = 2.2 h
Since train is overtaking, the motorbike so both are raveling in the same
directions and therefore the length of the train will be
40 x (100 – 64) x 5/18 (after converting)
= 400 m
Let Sudha can complete the work in q days
We know that they can complete the wok in 20 days
i.e. 1/p + 1/q = 1/20 ………………………. (i)
and p/2 + q/2 = 45 ………………………..(ii)
p + q = 90………………………………………….(iii)
From equation (i) and (iii)
pq = 1800
Now make the pairs from option whose sum would be 90 and multiplication would be 1800
So there is only one pair i.e. 60 x 30
And we know that Sudha is more efficient than the Asha, so Asha can do the work in 60 days.
