Question

A tube when full of water weight 35 kg but when 0.4 full of water weights 29 kg find the weight of the empty tube​

Answer 1

Answer:

25kg

Step-by-step explanation:

full= water + case weight = 35kg

0.4 full= water (0.4) +case=29 kg

by using algebra

assume A= water

B=case weight

A+B=35kg

4/10 A+B=29kg

you will get

4A+4B=140kg

4A+10B=290kg

6B=150kg

B=25kg
