IBPS SO Prelims Exam Model Paper 9

Given:
T = 15 hours
S’ = S –

S

4

Formula used:
Time = Distance/ Speed
Calculation:
T =

D

S

….(1)
⇒ D’ = D – 5
⇒ S’ = S × (1 – (

1

4

))
⇒ S’ =

3S

4

T =

(D–5)

( 3S 4 )

Replacing T by equation 1
⇒

D

S

=

(D–5)

(3 S 4 )

⇒ D – ((

3

4

) × D) = 5
⇒ D = 20 km
∴ Distance travelled by sohan is 20 km
