Calculation of Savings

To solve this problem, we need to calculate the savings of the older brother and the younger brother. Let's go step by step:

1) How much money did the older brother save? The older brother saved 0.5 of the total cost of the ball, which is 40 lts. Therefore, the amount of money saved by the older brother is 0.5 * 40 = 20 lts.

2) How much money did the younger brother save? The younger brother saved 0.4 of the total cost of the ball, which is 40 lts. Therefore, the amount of money saved by the younger brother is 0.4 * 40 = 16 lts.

3) How much money did the brothers have in total? To calculate the total amount of money the brothers had, we need to add up the savings of both brothers. The older brother saved 20 lts and the younger brother saved 16 lts. Therefore, the total amount of money the brothers had is 20 lts + 16 lts = 36 lts.

4) Will this amount be enough to buy the ball? The cost of the ball is 40 lts, and the brothers have a total of 36 lts. Therefore, the amount they saved is not enough to buy the ball.

In summary: 1) The older brother saved 20 lts. 2) The younger brother saved 16 lts. 3) The total amount of money the brothers had is 36 lts. 4) The amount they saved is not enough to buy the ball.
