TCS Company HR Interview Interview

A dealer originally bought 100 identical batteries at a total cost of q rupees. If each battery was sold at 50 percent above the original cost per battery, then, in terms of q, for how many rupees was each battery sold?

Read Solution (Total 4)

3q/200 rupees was each battery sold.

Cost of 1 battery = q/100
Each battery sold with profit 50% = q/100 + q/100*50/100
=q/100+q/200
=3q/200

Eg: Cost of each battery = 1rs. It means q = 100 (100*1 = 100)
==> Each battery sold with profit 50% . Therefore 1 battery = 1.50rs

Now put q=100 in 3q/200:
3(100)/200
300/200 = 1.50rs(Each battery rate. proved)

cost per battery=q/100
50% increase in the price per battery=q/100+(q/100)*(50/100)=3q/200=0.015q rs.

bought for q/100 dollars per battery ( as it is written there "originally" , tht means this amount doesnt include any profit of the dealer!)
each battery sold with profit 50% is
q/100 + q/100*50/100
=q/100+q/200
=3q/200
option A is correct

correct ans : 3q/200
Cost of 1 battery = q/100
Each battery sold with profit 50% = q/100 + q/100*50/100
=q/100+q/200
=3q/200
cost of 1 battery =3q/200

TCS Other Question

When a polygraph test is judged inconclusive, this is no reflection on the examinee. Rather, such a judgment means that the test has failed to show whether the examinee was truthful or untruthful. Nevertheless, employers will sometime refuse to hire a job applicant because of an inconclusive polygraph test result. Which of the following conclusions can most properly be drawn from the information above? Machine A produces bolts at a uniform rate of 120 every 40 second, and Machine B produces bolts at a uniform rate of 100 every 20 seconds. If the two machines run simultaneously, how many seconds will it take for them to produce a total of 200 bolts?
