Ratnam hired a car from a car renting agency which charges a flat amount of Rs. x for travelling up to 50 kilometres and Rs. y per km for every kilometer travelled thereafter. How much should Ratnam pay the agency for a journey of 70 kilometres?
a x + 70y

b x +20y

c 50x +20y

d 50 + 2y

Step-by-step explanation:

Notice that is per kilometer, which means depends on the number of kilometers traveled.

We know by given that the journey is 70 kilometers long, which means this number must multiply the variable.

Therefore, the right answer is A.

Correct option: b -> x + 20y

Step-by-step explanation:

From the first 50 kilometers, the price is a flat amount of x, and for the kilometers travelled thereafter, the price is y per kilometer.

If Ratnam travelled 70 kilometers, he needs to pay 'x' because of the first 50 kilometers, and (70 - 50) = 20 times y for the rest of the travel.

So the final price is:

x + 20y

Correct option: b

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%
