Question

17. A person being asked what time it
was answered:
The hours of the day which remain
are equal to one seventh of those
which have passed. What time was
it?
Choices:
(i) 9 P.M. (ii) 3 A. M.
(iii) 7 P.M. (iv) 8 P.M​

Answer 1

Step-by-step explanation:

let passed hours be x

then the remaining are 24-x

according to question

7x=24-x

8x=24

x=3

so the time is 3 am

as the time passed is 3 hrs.

Answer 2

9 p.m.

Let passed time=X

7X = 24 - X

8X = 24

X = 3

24 - 3 = 21 (in 24 hours time)

21 = 9 p.m.
