Question

Box 'A' weights 3 1/2 kg morethan Box 'B' , Box 'c' weights 2 3/4 kg morethan box 'B' . If the total weights are 39 kg. Find the weights of 3 each box

Answer 1

Answer:

A = B+3 1/2

C =B+2 3/4

A+B+C=39

B+3 1/2+B+B+2 3/4 = 39kg

3B+6 1/4 = 39

3B = 39-61/4

3B = 39-25/4

12B =156-25

12B =131

B =131/12=10 11/ 12. Ans

A =B+3 1/2 = I31/12+3 1/2

=131/12+7/2=(131+42) 12

173/i2 = 14 5/12: Ans

C=B+2 3/4

C=131/12+2 3/4

=131/12+1l/4

= I31/12 +33/12=164/12=13 2/3. Ans

Box A 14 5/12kg

Box B = 10 11 /12kg

Box C = .13 2/3kg
