Answer & Solution
Correct Answer:
Option
E
Let average expenditure of 19 people be x
then,
19x = 13 × 79 + 6 × (x + 4)
or, 19x = 13 × 79 + 6x + 24
or, x = 80.84
So, total money spent
= 80.84 × 19
= Rs. 1536.07
then,
19x = 13 × 79 + 6 × (x + 4)
or, 19x = 13 × 79 + 6x + 24
or, x = 80.84
So, total money spent
= 80.84 × 19
= Rs. 1536.07
