How much balance (in Rs) is left in Rajeev's account after 20 visits? 1. (a) 54 (b) 45
(c) 36
(d) 60

Answer 1

Answer:

For the 1st one - (c) 225-9t

2nd one - (b) 45

Step-by-step explanation:

1. Amount paid = Rs. 225

When Rs 9 is deducted for each visit,

Amount deducted for 't' days = 9t

Therefore, balance = Amount paid - 9t

x = 225-9t

2. Amount deducted each visit = Rs.9

Amount deducted in 20 visits = 20×9 = 180

Total amount paid = Rs. 225

Remaining balance = 225 - 180 = Rs.45
