Question

. Adrian earns $16000 per month. He spends 1/4 of his income on food, 3/10 of the

remainder on house rent and 5/21 of the remainder on the education of children. How

much money is still left with him?​

Answer 1

Answer:

I think $6400

Step-by-step explanation:

1/4 of $16000 = $4000

so remainder =$12000

3/10 of $ 12000 = $3600

so remainder = $8400

5/21 of $ 8400= $2000

so remainder = $6400

I'm not sure maybe I made some mistake in solution

Answer 2

Answer: $6400

Step-by-step explanation:

Income= $16000

∴ Amount spent on food = 1/4 of income

                                      = 1/4 × 16000

                                      = $4000

∴ Amount spent on house rent = 3/10 of the remainder

                                                = 3/10 × (16000 - 4000)

                                                = 3/10 × 12000

                                                = $3600

∴ Amount spent on education of children = 5/21 of the remainder

                                                                  = 5/21 ×  (16000 - 3600)

                                                                  = 5/21 ×  8400

                                                                  = $2000

∴ Amount left = $16000 - ($4000 + $3600 + $2000)

                       = $16000 - $9600

                       = $6400

∴ Adrian has $6400 left.
