Question

cucumber contains 99% water Ramesh 100 kg cucumber after 30 days of storing the cucumber Lose some water they now contain 98% water what is the total weight of cucumber now ​

Answer 1

Given:

Weight of the cucumber = 100 kg

99% weight of the cucumber is of water in it.

Percentage of water after 30 days = 98%

To Find:

Weight of the cucumber after 30 days.

Solution:

Weight of cucumber = 100 kg

Weight of water in cucumber = 99%

Rest material in cucumber = 100 - 99 = 1%

Therefore, weight of rest materials in cucumber = 100 × $\frac{1}{100}$ = 1 kg

Let the weight of cucumber after 30 days = w kg

Weight of water in cucumber after 30 days = 98% of w

                                                                        = 0.98w

Weight of rest materials which will remain constant even after 30 days

= w - 0.98w

= 0.02w

Equation for the weight of rest materials will be,

0.02w = 1

w = $\frac{1}{0.02}$

w = 50 kg
