QUESTION # 3
Ahmed requires 18. 1/2 feet long cable wire for a connection. He joined two lengths of wires of 9. 3/4 feet and 11. 1/6 feet. Now how much length does he have more than the required length ?
SOLUTION :
Requires length of a cable = 18. 1/2 feet
Length of 2nd part of cable = 9. 3/4 feet
Length of one part of cable = 11. 1/6 feet
Total length of joined parts = [ 9. 3/4 + 11. 1/6 ] feet
= 39/4 + 67/6
= 117 + 134 / 12
= 251 / 12 feet
Additional length = 251/ 12 - 18. 1/2
= 251 / 12 - 37 / 2
= 251 - 222 / 12
= 29 / 12
= 2. 5/12 feet
Hence, he has 2.5 / 12 feet more than required length .
QUESTION # 4
Salem,s salary is Rs. 12000. He gave 1/12th of his salary as aims,half of the reaming for house expenditures and 2/5th of the reaming as debt that was due upon him. What is the reaming salary with him ?
SOLUTION :
Salem 's salary = Rs. 12000
Amount of aims = 12000 × 1/ 12
= 1000
Remaining salary = 12000 - 1000 = 11000
House expenditures = 11000 / 2 = 5500
Remaining salary = 11000 - 5500
= 5500
Amount of debt = 5500 × 2/ 5
= 1100 × 2
= 2200 Rs
Remaining salary = 5500 - 2200 = 3300 Rs
Hence, the remaining salary of Salem is Rs 3300.
