(A) 250
(B) * 350
(C) 300
(D) * 340​

Answer 1

Answer:

350 rupees

Step-by-step explanation:

A= 392 R= 4% T = 3 year

$si = \frac{p \times r \times t}{100}$

$si = \frac{p \times 4 \times 3}{100}$

$si = \frac{12p}{100}$

$si = \frac{6p}{50}$

Amount = Principle + SI

$a = p + \frac{6p}{50}$

$392 = p (1 + \frac{6}{50} )$

$392 = p( \frac{56}{50} )$

$p = \frac{50 \times 392}{50}$

$p = 350$

this is right answer
