Answer 1

Answer:

Step-by-step explanation:

1.

Part 1: Amount for Karan:

SI = ( P * R * T )/100

SI = ( 7500 * 11 * 3.5 )/100

SI = 75* 11 * 3.5

SI = 2887.5

Amount after 3.5yrs = 10387.5rupees (sry I can't put the rupee symbol)

Part 1: Amount for Karim:

SI = ( P * R * T )/100

SI = ( 7500 * 11 * 4.5 )/100

SI = 75* 11 * 4.5

SI = 3712.5

Amount after 3.5yrs = 11212.5rupees (sry I can't put the rupee symbol)

Difference = 11212.5 - 10387.5 = 825 rupees
