A and B starts a business with Rs 2800 and Rs 5400 respectively. After 4 months C joins with Rs 4800. If after a year, the difference in the shares of A and C from the total profit is Rs 400, then what is the total profit?

A started from point P at 11 AM towards Point Q at 40 km/hr. also B started from point Q at 1 PM towards Point P at 50 km/hr. If points P and Q are 110 km apart, at what time do they meet?

Correct

Explanation:
A starts at 11 Am, after 2 hrs i.e. at 1 PM, he has covered distance = 2*40 = 80 km
Now B also started, distance between them is now 110-80 = 30 km
So time they meet = 1 PM + (30/(40+50)) = 1 PM + (1/3)*60 = 1:20 PM

Incorrect

Explanation:
A starts at 11 Am, after 2 hrs i.e. at 1 PM, he has covered distance = 2*40 = 80 km
Now B also started, distance between them is now 110-80 = 30 km
So time they meet = 1 PM + (30/(40+50)) = 1 PM + (1/3)*60 = 1:20 PM

Category: Quantitative Aptitude

20 men do a piece of work in 15 days. 30 women do the same piece of work in 20 days. In how many days will 2 m and 4w complete this work?

Correct

Explanation:
20 m in 15 days, so 2 m in (20*15)/2 = 150
30 w in 20 days, so 4 w in (30*20)/4 = 150
So 2m + 4w in 1/150 + 1/150 = 1/75

Incorrect

Explanation:
20 m in 15 days, so 2 m in (20*15)/2 = 150
30 w in 20 days, so 4 w in (30*20)/4 = 150
So 2m + 4w in 1/150 + 1/150 = 1/75

A can contains 34 l of milk. 4 litres of it is drawn out and 6 litres of water is poured in. If now again 6 litres of the mixture is taken out, what is the remaining quantity of milk in the mixture?

Correct

Explanation:
4 l drawn, milk = 34-4 = 30 l, water added 6 l
So ratio of milk to water is 30 : 6 = 5 : 1
Now 6 l of mixture taken out, so remaining milk is = 30 – (5/6) * 6 = 25

Incorrect

Explanation:
4 l drawn, milk = 34-4 = 30 l, water added 6 l
So ratio of milk to water is 30 : 6 = 5 : 1
Now 6 l of mixture taken out, so remaining milk is = 30 – (5/6) * 6 = 25

How many 5 digit numbers can be made from digits 4, 7, 3, 9, 0, 2, 1 when no digit repeats?

Correct

Explanation:
For a 5 digit number, 0 cannot be on first place, so total choices for 1st digit are 6,
Now at 2nd place 0 can also come, so total choices for 2nd digit are 6 again,
For 3rd = 5, for 4th = 4, for 5th = 3
So total numbers = 6*6*5*4*3 = 2160

Incorrect

Explanation:
For a 5 digit number, 0 cannot be on first place, so total choices for 1st digit are 6,
Now at 2nd place 0 can also come, so total choices for 2nd digit are 6 again,
For 3rd = 5, for 4th = 4, for 5th = 3
So total numbers = 6*6*5*4*3 = 2160
