Answer 1

Answer:

a. 6800/4 = 1700

b 6800-1700 = 5100* 1/4 = 1275

c 5100 - 1275 = 3825 * 1/9 = 435

Step-by-step explanation:

let money had be x

after salary x - 1x /4 = 3x/4 remaining

after electricity n water = 3x/4 - 3x/4 *1/4 = 9x/16 remaining

after transport 9x/16 - 9x/16 * 1/9 = 8x/16 = x/2 remaining

finally x /2 = 3400

x = 3400 " 2 = 6800
