Answer 1

Explanation:

Let the monthly income of Nikhil be Rs x. Nikhil invested 14% in shares and deposited 3% in a bank.

∴ Total investment = (14% + 3%) of x

= 17 % of x

= (17/100) × x

= 0.17x

Nikhil spent 5% on his children’s education and used 40% for his daily expenses.

∴ Total expenditure = (5% + 40%) of x

= 45% of x

= (45/100) × x

= 0.45x

Amount left with Nikhil = 19,000

Amount left with Nikhil = Income – (Total investment + Total expenditure)

∴ 19000 = x – (0.17x + 0.45x)

∴ 19000 = x – 0.62x,

∴ 19000 = 0.38x

$x = \frac{19000}{0.38} = \frac{19000 \times 1 00 }{0.38 \times 100} = \frac{1900000}{38}$

= 50000

∴ The monthly income of Nikhil is Rs 50000.

Answer 2

$\huge\mathtt\pink{ANSWER}$

Total Expenditure % = 5+14+3+40 = 62%

therefore total salary

= 38/100 × x = 19000

= 38x= 1900000

= x = 1900000/38

therefore x = 50,000

so the income of that man was ₹ 50,000 that month
