In this question, there is a typo in the table shown here. As per the official GATE 2019 question paper, the number of Mini rides in April is 70 (not 170). The solution uses 70, which is correct and gives the answer 23.97%. Please update the table accordingly to avoid confusion.

Answer 1

Percentage share of the revenue contributed by Prime to the total revenues of Mola for the entire duration of 4 months

$=\left ( \frac{1 \times\textrm{Rides given by Prime in 4 months duration}}{1 \times \textrm{Total number of rides in the 4 month duration}} \right ) \times100\%$

$=\left ( \frac{75+180+120+90}{170+320+215+190+110+220+180+70+75+180+120+90} \right )\times 100\%$

$=\left ( \frac{465}{1940} \right )\times 100\%$

$=23.97\%$

$\therefore$ Option B $23.97$

Answer 2

Percentage share of the revenue contributed by Prime to the total revenues of Mola for the entire duration of 4 months

$=\left ( \frac{1 \times\textrm{Rides given by Prime in 4 months duration}}{1 \times \textrm{Total number of rides in the 4 month duration}} \right ) \times100\%$

$=\left ( \frac{75+180+120+90}{170+320+215+190+110+220+180+70+75+180+120+90} \right )\times 100\%$

$=\left ( \frac{465}{1940} \right )\times 100\%$

$=23.97\%$

$\therefore$ Option B $23.97$
