Question (21) The yearly income of Simon is $250000. If Ryan earns 20% of 80% of yearly income of Simon per month, what is his income?
Solution:
Given, yearly income of Simon = $250000
Per month income of Ryan = 20% of 80% of yearly income of Simon
Therefore, yearly income of Ryan = ?
According to question,
Ryan's monthly income = 20% of 80% of Simon's yearly income
= 20% of 80% of 250000
`=20/100xx80/100xx250000`
= 20 × 80 × 25
= 40000
Thus, Ryan's monthly income = $40000
Therefore, Ryan's yearly income = $40000 × 12
[Since there are 12 months in a year]
= $480000
Thus, Ryan's yearly income = $480000 Answer
Question (22) The per kilogram price of potato is 80% of 90% of price of carrot. If the price of carrot is $50 per kilogram, then find the price of potato.
Solution
Given, price of carrot per kg = $50

= 8 × 9 × 0.5
= 72 × 0.5 = 36
Thus, price of potato per kg = $36 Answer
