Question

A treasure has 9.03 lb of gold coins and
8.4 lb of silver coins. The combined weight of all the coins is .

• A. 17.07 lb
• B. 17.77 lb
• C. 17.43 lb
• D. 17.34 lb

Answer 1

The correct option is C 17.43 lb

Weight of gold coins = 9.03 lb
Weight of silver coins = 8.4 lb

∴ Combined weight of all coins in the treasure = (9.03 + 8.4) lb

Now, we know, 8.4 = 8.40

Hence, the combined weight
= (9.03 + 8.4) lb
= (9.03 + 8.40) lb

Calculating 9.03 + 8.40 through place value table, we get:


So, we get, 9.03 + 8.40 = 17.43

∴ The combined weight of all the coins in the treasure is 17.43 lb.
