Answer:

for the first question: (C) 12hours

and the second question: (A) ₹4000

Step-by-step explanation:

FIRST QUESTION:

Given-

Journey distance s = 616 km

Train speed v = 112 km/hr

Halting time = 1 hr

Solution-

Time taken for A=>B,

t = s / v

t = 616 / 112

t = 5.5 hr

Train halts at station B for 1 hr before returning.

Train will take same time i.e. 5.5 hr to return.

Total journey time = 5.5 + 1 + 5.5 = 12 hr

Total time taken by train will be 12 hr.

SECOND QUESTION:

Let the CP be ₹x.

Then according to the given condition, we have

SP = ₹3360

Loss = 16%

Therefore to find CP,

x × (1 - 16/100) = 3360

x × (0.84) = 3360

or x = 3360/0.84

Therefore, x = ₹4000/-  

Hence, the cost price of the table is ₹4000/-
