2) Mr Ravi bought a washing machine for ₹ 15000 and sold it for ₹ 17000. find his profit or lost percent?​

Answer 1

Step-by-step explanation:

1] Given the speed of a person= 60 km

then,

Distance travelled in 4.5 hr

⇒ speed × time

⇒ 60 × 4.5=270

[ distance = 270 km ]

2] Cost price of the washing machine = ₹ 15000

    The selling price of the cycle = ₹ 17000

SP>CP ⟹ there is a gain.

⇒ 17000-15000=2000

g% = $\frac{2000}{15000}*100$

g% = 13.3%
