A vegetable seller bought one quintal of potatoes at rupees 35 per kg and sold at a loss of rupees 350,find rate of selling price.​

Step-by-step explanation:

cost price of 1 kg potatoes = 35 rupees

so, cost of 100 kg potatoes =

=》35 × 100

=》Rs. 3500

now, loss = Rs. 350

so, selling price = cost price - loss

=》3500 - 350

=》Rs. 3150

rate of selling price = 3150 ÷ 100

=》Rs. 31.5 per kg

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
