(ii) How many less symbols are needed to represent the number of students who applied in 2017 than those in 2015?

Options

A. `{:(i,ii),(12,4):}`
B. `{:(i,ii),(5,8):}`
C. `{:(i,ii),(8,4):}`
D. `{:(i,ii),(12,6):}`

Answer

A

Explanation

(i) No. of students applied in 2014 = 6000
`therefore` No. of symbols need to represent the students who applied in 2014 = 6000 = 500 = 12
(ii) No. of symbols needed to represent students who applied in 2017 = 5500 - 500 = 11
No. of symbols needed to represent students who applied in 2015 = 7500 - 500 = 15
`therefore 15 – 11 = 4 `less symbols are needed to represent the number of students applied in 2017 than those in 2015.
