28. The difference between the length and breadth of a rectangle is 23m. If its perimeter is 206m, then it's area is

(1) 2480 m²
(2) 2420 m²
(3) 1520 m²
(4) 2520 m²

Correct Answer: (4) 2520 m²

Solution:length of rectangle = x width = y

According to the question, x - y =23\ (i) Perimeter of rectangle = 2 (lenght + width) 2(x + y) = 206 x + y =103\ x + y = 103 x - y = 23 2x = 126 x = 63 metre .. 63 + y = 103 y = 103 - 63 y = 40 metre Area of rectangle = xy = 63 metre x 40 metre = 2520m ^ 2

29. Complete the series?

6, 8, 12, 20, 36

(1) 63
(2) 68

30. The age of father 10 years ago was thrice the age of his son. Ten years later, Father's age will be twice that of his son. The Ratio of their present ages is?

(1) 13:4
(2) 9:2
(3) 7:3
(4) 5:2

Correct Answer: (3) 7:3

Solution:let age of son = x

10 years ago, sonx-10 father = 3(x-10) Present age of 10 years hence, father's s = 3x - 30 + 10 = 3x - 20 10 years later son = x + 10 father = 3x-20+10 = 3x-10 According to the question, 3x - 10 = 2(x + 10) Rightarrow 3x - 10 = 2x + 20 ⇒ x = 30

Age of son = 30 Age of father = 3 x 30 - 20 = 70 father: son = 70 : 30 = 7:3
