First, let’s find the total amount of money Krishna has. Since each of the 64 boys receives Rs. 90, we can multiply 64 by 90 to get the total sum.
Next, let’s calculate the number of boys after a 25% increase. To find this, we can multiply 64 by (1 + 0.25) to account for the increase.
Finally, we can divide the total amount of money by the new number of boys to determine how much each boy will receive when the money is equally distributed among them.
