1. Study the following bar graph and the table carefully and answer the questions given below:
Time Taken (in hours) by 6 Vehicles on Two Different Days

Distance Covered (in km) by 6 Vehicles on Each Day

Vehicles Day 1 Day 2

A 832 864

B 516 774

C 693 810

D 552 765

E 935 546

F 703 636

The distance travelled by vehicle F on Day 2 was approximately what percent of the distance travelled by it on Day 1?

A. 80%

B. 65%

C. 85%

D. 95%

Solution:

\begin{aligned} Speeds of vehicles on Day 1: \\ A → \frac{832}{16} km/hr = 52 km/hr \\ B → \frac{516}{12} km/hr = 43 km/hr \\ C → \frac{693}{11} km/hr = 63 km/hr \\ D → \frac{552}{12} km/hr = 46 km/hr \\ E → \frac{935}{17} km/hr = 55 km/hr \\ F → \frac{703}{19} km/hr = 37 km/hr \\ Speed of vehicles on Day 2: \\ A → \frac{864}{16} km/hr = 54 km/hr \\ B → \frac{774}{18} km/hr = 43 km/hr \\ C → \frac{810}{18} km/hr = 45 km/hr \\ D → \frac{765}{15} km/hr = 51 km/hr \\ E → \frac{546}{14} km/hr = 39 km/hr \\ F → \frac{636}{12} km/hr = 53 km/hr \end{aligned}

\begin{aligned} Required % \\ = (\frac{636}{703} \times 100) % \\ = \frac{63600}{703} % \\ = 90.46 % \\ \approx 90 % \end{aligned}

Vehicles	Day 1	Day 2
A	832	864
B	516	774
C	693	810
D	552	765
E	935	546
F	703	636
