Answer:

The vendor should sell the potatoes at Rs. 9 per kg to gain 22%

Step-by-step explanation:

Total money spent by the vendor in purchasing the potatoes

= 25 × 7 + 15 × 8

= 175 + 120

= 295 Rs.

Toal kg of potatoes = 25 + 15 = 40 kg

In order to make the profit of 22%, he should gain amount

= 295 + 295 × 22/100

= 1.22 × 295

= 359.9 Rs.

Therefore, he should sell the potato at the rate

= 359.9/40

= 8.99

≈ 9 Rs. /kg

Therefore, the vendor should sell the potatoes at Rs. 9 per kg to gain 22%
