Answers :
1) Answer: A
25.03% of 247.91 – 15.18% of 140.05 = ?
62 – 21 = ?
? = 41
2) Answer: D
(82.01 * √50) ÷ ? = 287.08
574 /? = 287
? = 2
3) Answer: A
(16.51 * 11.98) ÷ 6 = ? + √170
204/6 = ? + 13
? = 21
4) Answer: E
959.91 ÷ 24.09 = 37.08 + (? ÷ 3)
40 – 37 = ?/3
? = 9
5) Answer: A
(17.03)2 + (30.98)2 – (8.89)3 = ?
289 + 961 – 729 = ?
? = 521
6) Answer: C
Compound Interest = Rs 10500
P*((1+10/100)2-1) = Rs 10500
P(1.21-1) = Rs 10500
P= 10500/0.21
P = Rs 50,000
SI = 50000*10*2/100
SI = Rs 10,000
(Or)
CI at 10% pa for 2 years =
= 21%
21% = 10500
SI at 10% for 2 years is equivalent to 10 x 2 = 20%
20% = 10500/21 x 20 = 10000
7) Answer: C
Side of the square = √784=28 cm
Radius = 28/2=14 cm
Perimeter of the semicircle = πr+2r
= (22/7 x 14+2 x 14)= 44+28=72 cm
8) Answer: C
Jatin + Piyush + Suraj = 160
Now, 16 years ago,
Jatin -16 : Piyush -16 : Suraj – 16 = 1:3:4
160 – 48 = 112
Suraj’s age 16 years ago = 112 x 4/8=56
Suraj’s present age = 56 + 16 = 72 years
9) Answer: D
According to question,
10) Answer: D
Let the number be 5X, 10X and 19X.
According to question,
5X + 19X – 10X = 140
24X -10X = 140
14X = 140
X = 10
The smallest number = 5 x 10 = 50
