प्रश्न
If Naresh walks 250 steps to cover a distance of 200 metres, find the distance travelled in 350 steps.
उत्तर
∵ Naresh walks 250 steps to cover distance = 2000 m
∴ in 1 step, he covers the distance = `200/2500 m`
∵ In 350, steps, he covers = `200/250 xx 350`
= `(20 xx 350)/25`
= `7000/25`
= 280 m
