Explanation

Increass in the number of engineers,
Company `V rarr (400xx130)/(100)=250`
Company `X=rArr (700xx135)/(100)=945`
Company `Y rArr (950xx140)/(100=1330`
Total engineers `=250+945+1330+650+750+=4195`
Total original number of engineers `=400+650+700+950++750=3450`
Percentage increases
`=(4195-3450)/(3450)xx100=21.59%`
`~~=22%`
