Answer 1

$<b>Heya mate. (^_-). Solution below.$
====================================

[] Let Gopal's monthly income be 'x'.



[] Then, monthly expenditure,

= 81% of total

= 81/100 × x

= 81x/100



[] And, monthly saving,

= total income - monthly expenditure.

= x - 81x/100

= (100x - 81x)/100

= 19x/100



[] But, according to the question, his monthly savings is 3534 Rs.

→→→ 19x/100 = 3534

=> x = 3534 × 100/19

=> x = 353400/19

=> x = 18600


•°• His monthly income is Rs. 18600 (option A)
