Answer 2

Answer:

(a) 7/20

(b) ₹ 450

Step-by-step explanation:

(a) Varun spent 1/4 and 2/5 of his total money

$\frac{1}{4} +\frac{2}{5} = \frac{5 + 8}{20} \\\\=> \frac{13}{20}$

So, spent was 13/20

Now, The total he had initially will be 1 (A complete fraction)

Hence, savings = income - spent

$=> Savings = 1 - \frac{13}{20} \\\\=> Savings = \frac{7}{20}$

(b) Book cost was ₹ 180. It was 2/5 part of income

Now, if the income is x, then,

$\frac{2}{5} \times x = 180 \\\\=> 2x = 900 \\\\=> x = 450$

Total income is x = 450

Total money he had is ₹ 450
