प्रश्न
For 100 km, a taxi charges ₹ 1,800. How much will it charge for a journey of 120 km?
उत्तर
Let a charge of a car is ₹ x in 120 km
| Distance in(km) | 1800 | x |
| Taxi charges (₹) | 100 | 120 |
Since it is the case of direct variation
`⇒"x"_1/"y"_1="x"_2/"y"_2`
`⇒1800/100xx"x"/120`
⇒ 100x = 1800 × 120
`"x"=(1800xx120)/100`
= ₹2160
