Data Interpretation Ques 380
Directions : The following tables show the particulars of travel by four different cars along four different routes between the cities X and Y. Consider the following information carefully and answer the questions.
| Cars | Maximum Speed |
Speed of the cars only when all seats are filled |
Routes | Distance | Percentage of speed reduction due to traffic |
|---|---|---|---|---|---|
| Suzuki | $220 km / h$ | 160 | A | 300 | $10 \%$ |
| TATA | $240 km / h$ | 150 | B | 280 | $18 \%$ |
| Honda | $260 km/h$ | 170 | $\mathbf{C}$ | 320 | $15%$ |
| Hyundai | $200 km / h$ | 140 | D | 310 | $20 \%$ |
NOTE: All the cars travel between Cities X and Y via any one of the routes given above.
What is the approximate average speed of the cars Suzuki with all seats filled along route B, TATA with only one seat filled along route $A$ and Honda with all seats filled along route $C$ ?
(1) $150 km / h$
(2) $125 km / h$
(3) $127 km / h$
(4) $196 km / h$
(5) $164 km / h$
Show Answer
Correct Answer: 5
Solution: (5) Speed of Suzuki along route B
$=160 \times 82 \%=\frac{160 \times 82}{100}$
$\approx 131 km / h$
Speed of TATA along route A
$=240 \times 90 \%=\frac{240 \times 90}{100}$ $=216 \text{ km/h}$
Speed of Honda along route C
$=170 \times 0.85 \%=144.5 km / h$
Required average speed
$=\left(\frac{131+216+144.5}{3}\right)=\frac{491.5}{3}$
$\approx 164 km / h$
