Question

19. Sakshi can do a piece of work in 20
days. Tanya is 25% more efficient
than Sakshi. The number of days
taken by Tanya to do the same
piece of work is
(a) 15 (b) 16 (c) 18 (d) 25​

Answer 1

Answer:

option - b (16)

Step-by-step explanation:

Ratio of times taken by Sakshi and Tanya

= 125 : 100

= 5 : 4

Suppose Tanya takes x days to do the work

5 : 4 :: 20 : x

⇒ x=4×205

⇒ x = 16 days

Hence, Tanya takes 16 days to complete the work
