The average of runs of a cricket player of 20 innings was 36. How many runs must he make in his next innings so as to increase his average of runs by 4 ? | [
"106",
"122",
"116",
"120"
] | D | Average = total runs / no.of innings = 36
So, total = Average x no.of innings = 36 * 20 = 720
Now increase in avg = 4 runs. So, new avg = 36+4 = 40 runs
Total runs = new avg x new no. of innings = 40 * 21 = 840
Runs made in the 11th inning = 840-720 = 120

So, the number of items defective in brand A=x*40, in brand B=0.06*35 and brand C=0.08*25
Total number of widgets=40+35+25=100
the probability that the widget selected is defective is 0.063=(x*40+0.06*35+0.08*25)/100

= 3 (2 (4 + x) - 3) - 5(x + 1)
= 3 (8 + 2 x - 3) -5 x - 5
= 3 (2 x + 5) - 5x -5
