How does sprinkling of salt help in clearing the snow covered roads in hilly areas?
Show Hint
Freezing point depression is a colligative property, meaning it depends on the number of solute particles.

Solution and Explanation
Sprinkling salt lowers the freezing point of water, which helps in melting the snow and ice on the roads. This is due to the phenomenon known as freezing point depression, where the presence of salt disrupts the formation of ice crystals, leading to the melting of snow and ice even at lower temperatures.

Rupal, Shanu and Trisha were partners in a firm sharing profits and losses in the ratio of 4:3:1. Their Balance Sheet as at 31st March, 2024 was as follows:
(i) Trisha's share of profit was entirely taken by Shanu.
(ii) Fixed assets were found to be undervalued by Rs 2,40,000.
(iii) Stock was revalued at Rs 2,00,000.
(iv) Goodwill of the firm was valued at Rs 8,00,000 on Trisha's retirement.
(v) The total capital of the new firm was fixed at Rs 16,00,000 which was adjusted according to the new profit sharing ratio of the partners. For this necessary cash was paid off or brought in by the partners as the case may be.
