Answer:-

1.Sol:- (3)

Ram: Shyaam = 3: 5    (7 year ago)
Ram: Shyaam = 5: 7    (9 year hence)
2 ratio = 16
1 ratio = 8
Ram’s present age = 8 x 3 + 7 = 31
Ram’s age 6 hence = 31 + 6 = 37 yr.
Sohan’s age 6 year hence = 12 + 3+ 6 = 21 year
Required ratio = 37 : 21

2.Sol:- (2)


SSC-CGL-MATHS-22-01-2020 , SSC-CGL-MATHS-22-01-2020
SSC-CGL-MATHS-22-01-2020
SSC-CGL-MATHS-22-01-2020
SSC-CGL-MATHS-22-01-2020 


3.Sol:- (1)

Let CP = 100x
So,
100x – 1134 = 10x
90x = 1134 ,
100x = CP = 1260
Profit percent = SSC-CGL-MATHS-22-01-2020


4. Sol. (B) 

SSC-CGL-MATHS-22-01-2020
∠OAB SSC-CGL-MATHS-22-01-2020
∠OAB= 20o


5. Sol. (A)

SSC-CGL-MATHS-22-01-2020

6. Sol. (C)

=1354.24

7. Sol. (A)

LCM = 2×2×2×3×3×5 = 360
360 × 2 = 720+8 = 728
728 ÷ 13 = 56
Correct number is 728
Sum of these digits is 17


7.हल :-

लo स o = 2×2×2×3×3×5 = 360
360 × 2 = 720+8 = 728
728 ÷ 13 = 56
सही संख्या=  728
अंको का योग = 17


8.Sol:-  (3)

SSC-CGL-MATHS-22-01-2020 -------- (1)
SSC-CGL-MATHS-22-01-2020 ---------(2)
Subtract after squaring of both equation,
SSC-CGL-MATHS-22-01-2020
SSC-CGL-MATHS-22-01-2020
SSC-CGL-MATHS-22-01-2020 = SSC-CGL-MATHS-22-01-2020 = SSC-CGL-MATHS-22-01-2020
= SSC-CGL-MATHS-22-01-2020


9.Sol:- (1)

As we know
BIC = 90 + A/2
125 = 90 + A/2
SSC-CGL-MATHS-22-01-2020
Angle made cintre of the circle is twice the angle made on circumference.
किसी वाह्य वृतीय त्रिभुज में केंद्र पर बना कोण परिधि के कोण का दुगना होता है
Angle BOC =  140
Required ratio = 140 : 125
= 28 : 25 


10.Sol:- (1)

SSC-CGL-MATHS-22-01-2020
After solving,
x = 2/3 , y = -1 ,  z = 5/4
= SSC-CGL-MATHS-22-01-2020 
= 2 – 6 + 5
= 1
