- The time taken by a boat to cover ‘x’ km upstream at speed of ‘u’ km/hr. is same as the time taken by it to cover 80 km downstream at speed ‘v’ km/hr. If u:v = 4:5 resp. Find the value of x.
5077728164Option E

u:v = x:80

4:5 = x:80

=>x = 64 - The speed of a boat in still water in 22 km/hr and the rate of current is 4 km/hr. The distance travelled downstream in 24 minutes is:
11.9 km14.5 km16.6 km10.4 km12.2 kmOption D

Speed downstream = (22 + 4) = 26 kmph

Time = 24 minutes =24/60 hour

Distance travelled = Time × speed = 2/5×26 = 10.4 km - Two bikes A and B were sold at Rs.60,000 each. If bike A was sold at 20% profit and B was sold at 20% loss.What is the difference between the cost price of both the bikes?
2300020000250003100033000Option C

CP(A) = 60000/1.2 = 50000

CP(B) = 60000/0.8 = 75000

Difference = 75000-50000 = Rs.25000 - Murali purchased 20 dozens of toys at the rate of Rs. 375per dozen. He sold each one of them at the rate of Rs. 33. Find out his profit percentage.
5.6%4.9%3.2%4.4%3.9%Option A

cost price of 12 toys =375

selling price of 12 toys =33×12=396

profit =396−375=21

profit percentage = [21×100]/375

=7×4/5=5.6% - P is able to do a piece of work in 15 days and Q can do the same work in 20 days. If they can work together for 4 days, what is the fraction of work left?
9/148/156/136/117/19Option B

Amount of work P can do in 1 day = 1/15

Amount of work Q can do in 1 day = 1/20

Amount of work P and Q can do in 1 day = 1/15 + 1/20 = 7/60

Amount of work P and Q can together do in 4 days = 4 × (7/60) = 7/15

Fraction of work left = 1 – 7/15= 8/15 - 53,61,81,?,157,213
