The difference between the interests Poonam earns from both the Schemes at the end of 2 years is Rs 294/-. what is the value of P ?
Correct Answer: Description for Correct answer:
According to question,
\( \Large \frac{4200 x 12x 2}{100} \) - (4200 - P)[\( \large 1 + \frac{10}{100}^{2} \) - 1] = 294
1008 - ( 4200 - P)[\( \Large \frac{121 - 100}{100} \) ] = 294
(4200 - P) x \( \Large \frac{21}{100} \) = 1008 - 294
(4200 - P) x \( \Large \frac{21}{100} \) = 714
4200 - P = 3400
P = Rs 800/-
