Question

friend help me pls it is request to you ​

Answer 1

Answer:

• a) Rs. 36,000

• b) 14months or 1yr and 2 months

Step-by-step explanation:

Time = 8 months

Earning = 24,000

Earnings per month = 24000/8 = 3,000

a) Earnings in 1yr or 12months = 3,000*12 = 36,000

b) Total earnings = 42,000

Time taken to earn it = 42000/3000 = 14 months.

Answer 2

Answer:

a]Money earned in 8 months=Rs.24,000

Thus, money earned in 1 month=Rs.24000/8

                                                    =Rs.3000

1 year = 12 months

thus, money earned by Amit in 1 year or 12 months=Rs. 3000*12

                                                                                    =Rs.36,000

                                                   OR

you can also do this by direct and inverse variation

 money              time

24000                 8 months

x                           12 months

it is a direct variation

thus ,

x1/y1=x2/y2

24000/8=x/12

24000*12/8=x

3000*12=x

36000=x

b] time took by amit to earn Rs.24000=8 months

time took by amit to earn 1 rupee=8/24000

                                                       =1/3000

thus time took by amit ti earn Rs.48000=1/3000*48000

                                                                   =16 months

                                                                    = 1 year 4 months

                                                  OR

again you can also solve this using direct or inverse variation

thus

money     time

24000      8 months

48000        x months

thus it is an direct variation

thus

x1/y1=x2/y2

24000/8=48000/x

3000x=48000

x=48000/3000

x=16 months

x=1 year 4 months
