576

625

529

484

676

Solution:

Let four numbers in increasing order is a, b, c & d

ATQ,

a + b + c + d = 4 x 26 = 104

a +d = 55

⇒ b + c = 49

c – b = 1

b = 24, c= 25

b² = 576

ATQ,

a + b + c + d = 4 x 26 = 104

a +d = 55

⇒ b + c = 49

c – b = 1

b = 24, c= 25

b² = 576

**Directions (11-15): In the following questions, two equations in x and y are given. Solve these equations and give answer**

**Q11. I. 2x+3y=14**

**II. 4x+2y=16**

if x>y

if x <y

if x≥y

if x≤y

x=y or relation cannot be established between x and y

Solution:

I. 2x + 3y = 14

II. 2x + y = 8

Solving I and II,

we get x = 2.5, y = 3

y > x

II. 2x + y = 8

Solving I and II,

we get x = 2.5, y = 3

y > x

**Q12. I. 6x²+77x+121=0**

**II. y²+9y-22=0**

if x>y

if x<y

if x≥y

if x≤y

x=y or relation cannot be established between x and y

**Q13. I. 6x²+41x+63=0**

**II. 12y²+55y+63=0**

if x>y

if x<y

if x≥y

if x≤y

x=y or relation cannot be established between x and y

**Q14. I. 4x²+11x+6=0**

**II. 2y²+11y+15=0**

if x>y

if x<y

if x≥y

if x≤y

x=y or relation cannot be established between x and y

**Q15. I. 10x²-7x+1=0**

**II. 35y²-12y+1=0**

if x>y

if x<y

if x≥y
