1)

What is the ratio of the speeds of vehicle D and vehicle E on day 2?


A) 15 :13

B) 17 :13

C) 13 : 11

D) 17 :1.4

E) None of these

Answer:

Option B

Explanation:

Speeds of vehicles on Day 1:

A → $\frac{832}{16}$ = 52 Km/hr

B → $\frac{516}{12}$ = 43 Km/hr

C → $\frac{693}{11}$ = 63 Km/hr

D → $\frac{552}{12}$ = 46 Km/hr

E → $\frac{935}{17}$ = 55 Km/hr

F → $\frac{703}{19}$ = 37 Km/hr

Speeds of vehicles on Day 2:

A → $\frac{864}{16}$ = 54 Km/hr

B → $\frac{774}{18}$ = 43 Km/hr

C → $\frac{810}{18}$ = 45 Km/hr

D → $\frac{765}{15}$ = 51 Km/hr

E → $\frac{546}{14}$ = 39 Km/hr

F → $\frac{636}{12}$ = 53 Km/hr

Required ratio

= $\frac{Speed of D on day 2}{Speed of E on day 2 }$

= $\frac{51}{39}$ = $\frac{17}{13}$ = 17:13
