Question

Divide rupees 1380 among A,B and C so that the amount received by A is five times as much as B' S share and three times as C'S share . find share of A,B and C

Answer 1

Answer:

A = 900, B = 180, C = 300

Step-by-step explanation:

A=5B................(1)

A=3C................(2)

A+B+C=1380......(3)

Putting values of B and C from 1 and 2 in 3, we get

⇒A + (A/5) + (A/3) = 1380

⇒ (15A+ 3A + 5A)/15 = 1380

⇒23A= 1380×15

⇒A = 1380×15/23 = 900

hence B=A/5 = 90/5 = 180

C=A/3 = 90/3=300

Answer 2

Answer:A = 900,B =180,C =300

Step-by-step explanation:

A=5(B),1/5A = B

A= 3(C),1/3A =C

A+B+C =1380

A+ 1/5A+ 1/3A = 1380

15(A)+ 03(A) +05(A)/15 =1380

23(A)/15 =1380

A = 1380×15/23

A=900

B=1/5(900) =180

C=1/3(900) = 300

900+180+300= 1380
