I had 2000 shillings, I sold six clocks at sh.900 each. How much money did I have altogether?

To find out how much money you had altogether, you need to calculate the total amount you received from selling the clocks and then add it to the amount you originally had.

Total amount received from selling 6 clocks = 6 x 900 shillings = 5400 shillings

Money you had altogether = Original amount + Total amount received = 2000 shillings + 5400 shillings = 7400 shillings

Therefore, you had 7400 shillings altogether.
