to raise money for charity. Tony will raise Rs. 20, plus Rs. 2 for
each lap he jogs. Sunil will raise Rs. 30, plus Rs.1.50 for each lap he jogs. The total amount of money each
will raise can be calculated using the follwing expressions where n represents the number of laps run :
Tony : 20 + 2n ; Sunil : 30 + 1.50n
After how many laps will they have raised the same amount of money?
(A) 3 (B) 6.5 (C) 14.5 (D) 20

Let laps be n

20+2n = 30+1.5n

0.5 n = 10

n = 20 laps

after 20 laps,they raise same money of rs. 60 each
