Answer 1

Gain per Rs 1, 000 of investment
           

  = 90,000/2,15,000 * 100

investment :  Rs 1, 40, 000
 
 Rate of interest = 8% 
C.I.
 
 period = 2  years
 
 Maturity amount =

A = Rs 1,40,000 * (1 + 8/100)²
     
= 1,40,000 * 1.08²
   
  = Rs 1, 63, 296
 
Amount (interest) gained in 2 years

= Rs 23, 296.

amount gained per 1000 of investment
     

  = 23, 296/1,40,000 * 100

Answer 2

Answer:

hira lal gain 41.86%

ramnik lal gain = 16.64%

hiralal investment was more profitable

Step-by-step explanation:

ramnik lal investment 140000

8% compounded

1 year

interest = 140000*8/100 = 11200

amount after 1 year = 140000+ 11200 = 151200

2nd year interest = 151200*8/100 = 12096

amount after 2 year = 151200+12096 = 163296

Gain= 163296-140000= 23296

Gain% = (23296/140000)*100= 16.64 %

Hiralal invested 215000

amount got 305000

Gain = 305000-215000 = 90000

Gain % = (90000/215000)*100 = 41.86%

hiralal investment was more profitable
