In order to earn a total of $400 in 4 shifts, he should earn $100 in each shift
For each shift, there are 4 hrs
for 1 hr --> earn $4
for 4 hrs --> earn $x
x = 4*4 = $16
so he earns $16 in 1 shift in 4hrs... so he has to earn $84 through calls...ie ($100 - $16)

For 1 call --> earns $4
for x call - -> $84
x= 84/4 * 1 = 21 calls


Ans : 21 calls

$4 per hour so $4* 4 Shift=$16*4 Shift=$64
Now 400-64=336 rest
now 4 Shift*$x=336
X=$84
now$4 per call now john received call=84/4=21 call

4shifts= 4*4=16 hours.
in 16 hrs he earned 16*4=64

answer will be 84
since for 4 shifts he will get 4*16 for hours as fix so 64
now total 400 - 64 = 336/4 = 84 no. of calls
