The correct option is C 1.3
We want to find 600,000+100bu+300,000
Lets take the original expression given 6000=bu+2000
From here we can find value of bu
bu=6000−2000
bu=4000
We now plug the value of bu in the expression =600,000+100×4000+300,000
=600,000+400,000+300,000
=1,300,000
The correct answer is 1.3 millions.
