There are 23 Kids in a classroom. 12 Kids are wearing socks and 8 are wearing Shoes. 6 Kids are wearing both.
How many are Bare Feet ? | [
"8",
"4",
"5",
"9"
] | D | 12 kids wear socks
8 kids wear shoes
6 wear both.
12 – 6 = 6 (wear only socks)
8 – 6 = 2 (wear only shoes)
6 (wear both)
hence, 23 -14 = 9
9 kids are with bare feet.

The average of runs of a cricket player of 10 innings was 33. How many runs must he make in his next innings so as to increase his average of runs by 4 ? | [
"85",
"79",
"89",
"77"
] | D | Explanation:
Average = total runs / no.of innings = 33
So, total = Average x no.of innings = 33 x 10 = 330.
Now increase in avg = 4runs. So, new avg = 33+4 = 37runs
Total runs = new avg x new no. of innings = 37 x 11 = 407
Runs made in the 11th inning = 407 - 330 = 77 Answer: A | AquaRat_train |

For the first quarter, he pays 10% of 10,000 which is $1000.
So for the four quarters in the year, he will approximately play 1000*4=4000 over the entire year.
Because of compound interest it will be more than 4000. Approx. option E is correct.
