Answer 1

Answer:

(B) 42

Step-by-step explanation:

Cost price is ₹39

profit% is 50/7%

Selling price=39+39×50/700

=39+2.78

=₹41.78 Or ₹42 (approximate.)

Answer 2

Option 'b' is correct.

Step-by-step explanation:

Since we have given that

Cost price = Rs. 39

Let the selling price be 'x'.

Profit = $\dfrac{50}{700}x=\dfrac{5}{70}=\dfrac{1}{14}$

According to question,

$x-39=\dfrac{x}{14}\\\\x-\dfrac{x}{14}=39\\\\\dfrac{14x-1x}{14}=39\\\\\dfrac{13x}{14}=39\\\\x=\dfrac{39\times 14}{13}\\\\x=3\times 14\\\\x=Rs.\ 42$

Hence, Option 'b' is correct.
