Answer Key-

Q-(1) Sol-(4)

80% of 20 + 66.66% of 324 + 60% of 35 = ?
16 +2├Ч324/3+ 21 = ?
16 + 216 + 21 = ?
? = 253

Q-(2) Sol-(1)
(?)2 + 93 = 312 тАУ 7
(?)2 + 729 = 961 тАУ 7
(?)2 = 225
? = 15

Q-(3) Sol-(2)

(30)2 тАУ (28)2 тАУ (36)2 + (10)3 тАУ (9)3 = ?
900 тАУ 784 тАУ 1296 + 1000 тАУ 729 = ?
? = тАУ 909

Q-(4) Sol-(5)

67 ├Ч 25 + 22 ├Ч 29 + 31 ├Ч 35 = ? ├Ч 11 + 10
1675 + 638 + 1085 = ? ├Ч 11 + 10
? ├Ч 11 = 3388
? = 308

Q-(5) Sol-(3)
60 + 135 = ? + 50 тАУ 23
? = 168

Q-(6) Sol-(4)
Let the total population of India in 2019 = x million
then 20% of x million = 100 million
x = 100 ├Ч 5 = 500 million
2% of the total population of India sold products online = 2% of 500 million
= 10 million

Q-(7) Sol-(4)
Let the total population of India in 2019 = x million then
20% of x million = 100 million
x = 100 ├Ч 5 = 500 million
2% of the total population of India sold products online = 2% of 500 million = 10 million
In 2020, the number of sellers remained constant then in 2020, the revenue per sellers=5000

Q-(8) Sol-(2)

In 2019, 100 million people bought products online
In 2020, 120% of 100 = 120 million people brought products online
In 2021, 130% of 120 = 13 ├Ч 12 = 156 million people will buy products online

Q-(9) Sol-(2)

Let the smallest number be x
= x + x+1 + x+2 + x+3 + x+4
= 5x + 10 = 8(x + 4) + 2
x = - 24/3
x = - 8

Q-(10) Sol-(3)
Work done by P in 10 days = 40% = 2/5
Or, work done by P in 1 day = 1/25
Work done by Q in 18 days = 75% = ┬╛
Or, work done by Q in 1 day = 1/24
Work done by P and Q together = 1/25 + 1/24 = 49/600
Let P left the work after x days
Or, work done by P and Q in x days = 49x/600
Then, Q worked alone for 3 days = 3 ├Ч 1/24 = 1/8
Since, 63% of the work is still left, total work done = 100% - 63% = 37% = 37/100
49x/600 + 1/8 = 37/200
(49x + 75)/600 = 37/100
49x + 75 = 222
x = 147/49 = 3
