Answer 1

Number of upper primary pupils who took part in the sports meet in 2016 is 1478.

Explanation:

Total number of upper primary pupils who took part in the sports meet in 2014 is 1760. It was decreased of 20% compared to 2015.

So that,

20% of 1760 =
`(20)/(100)` x 1760

= 0.2 x 1760

= 352

Number of upper primary pupils who took part in the sports meet in 2015 = 1760 - 352

= 1408

Also,

5% of 1408 =
`(5)/(100)` x 1408

= 0.05 x 1408

= 70.4

Number of upper primary pupils who took part in the sports meet in 2016 = 1408 + 70.4

= 1478.4

With an increase of 5% compared to 2015, the number of upper primary pupils who took part in the sports meet in 2016 is 1478.
