Mola is a digital platform for taxis in a city. It offers three types of rides – Pool, Mini and Prime. The table below presents the number of rides for the past four months. The platform earns one US dollar per ride. What is the percentage share of revenue contributed by Prime to the total revenues of Mola, for the entire duration?

23.97

16.24

38.74
 25.86
Correct Option: A
Here,
Revenue shared by pool = 170 + 320 + 215 + 190 = 895$
Similarly,
Revenue shared by mini = 110 + 220 + 180 + 70 = 580$
and,
Revenue shared by prime = 75 + 180 + 120 + 90 = 465$
Now, percentage share of revenue contributed by prime
=  = 23.97%  
895 + 580 + 465 
 If IMHO = JNIP; IDK = JEL; and SO = TP, then IDC =
 JDC

JED

JCD
 JDE
Correct Option: B
For IMHO = JNIP
I + 1 = J
M + 1 = N
H + 1 = I
O + 1 = P
For
SO = TP
S + 1 = T
O + 1 = P
Similarly, for IDC = JED
I + 1 = J
D + 1 = E
C + 1 = D

A firm hires employees at five different skill levels P, Q, R, S, T. The shares of employment at these skill levels of total employment in 2010 is given in the pie chart as shown. There were a total of 600 employees in 2010 and the total employment increased by 15% from 2010 to 2016. The total employment at skill levels P, Q and R remained unchanged during t hi s period. I f t he exmployment at skill level S increased by 40% from 2010 to 2016, how many employees were there at skill level T in 2016?

72

60

30
 35
Correct Option: B
P = 20% = 120% →(↑15%) 1.15 × 600
P = 25% = 150 →(↑0%) 150
R = 25% = 150 →(↑0%) 150
S = 25% = 150 →(↑40%) 210
T = 5% = 30 → ?
Now, employees at skill level T in 2016,
= 690 – (120 +150 + 150 + 210) = 60

A person divided an amount of Rs. 100,000 into two parts and invested in two different schemes. In one he got 10% profit and in the other he got 12%. If the profit percentages are interchanged with these investments he would have got Rs. 120 less. Find the ratio between hi s investments in the two schemes.

9: 16

47: 53

11: 14
 37: 63
Correct Option: B
Let the first part = x
So second part = 100,000x
According to question,
[0.1x + 0.12(100,000 – x)] – [0.12x + 0.1(1000,000 – x)] = 120
⇒ 0.2x – 0.24x + 1200 – 1000 = 120
⇒ – 0.04x = – 1880 x = 47000
=  =  
100,000  x  53000  53 

A worker noticed that the hour hand on the factory clock had moved by 225 degrees during her stay at the factory. For how long did she stay in the factory?

8.5 hours

3.75 hours

4 hours and 15 minutes
 7.5 hours
Correct Option: D
Since, we know that 360° = 12 hours
∴ 10 =  hours  
360 
∴ 225° =  hours  
360 
= 7.5 hours
