Dear Students!!! There is most general as well as a scoring section in all the competitive entrance examinations in the teaching field i.e “Mathematics”.
Because in this section only one thing is work i.e your accuracy and that could be nourished with the daily practice.With proper system, Study Notes, Quizzes, Vocabulary one can quiet his/her nerves and exceed expectations in the blink of an eye. So, for this, we are providing you the daily quiz for all teaching exams i.e CTET Exam 2019

(a) Rs. 7000
(b) Rs. 12000
(c) Rs. 14000
(d) Rs. 15000

(a) 18750 sq. m
(b) 37500 sq. m
(c) 40000 sq. m
(d) 48000 sq. m
Q9. The ratio between the length and the perimeter of a rectangular plot is 1 : 3. What is the ratio between the length and breadth of the plot?
(a) 1 : 2
(b) 2 : 1
(c) 3 : 2
(d) Data inadequate
Q10. The ratio between the length and the breadth of a rectangular park is 3 : 2. If a man cycling along the boundary of the park at the speed of 12 km/hr completes one round in 8 minutes, then the area of the park (in sq. m) is
(a) 15360 sq. m
(b) 153600 sq. m
(c) 30720 sq. m
(d)307200 sq. m
Sol. Let the breadth of the rectangle be x metres.
Then, length of the rectangle = (2x) metres.
2 (2x + x) = 60 ⇒ 6x = 60 ⇒ x = 10.
So, length = 20 m, breadth = 10 m.
∴ Area = (20 × 10) m² = 200 m².
Sol. Let the length and breadth of the field be l and b km respectively.
Then, 2 (l + b) = 6 or l + b = 3 and lb = 2.
(l – b)² = (l + b)² – 4 lb = 3² – 4 × 2 = 1 ⇒ (l – b) = 1 m
Sol. Let the length and breadth of the rectangle be (9x) cm and (7x) cm respectively.
Then, 9x × 7x = 252 ⇒ 63 x² = 252 ⇒ x² = 4 ⇒ x = 2
So, length = 18 cm, breadth = 14 cm.
∴ Perimeter = 2 (18 + 14) cm = 64 cm
Sol. Let the width of the table be x feet. Then, length of the table = (x + 4) ft.
∴ x (x + 4) = 45 ⇒ x² + 4x – 45 = 0
⇒ x² + 9x – 5x – 45 = 0
⇒ x (x + 9) – 5 (x + 9) = 0
⇒ (x + 9) (x – 5) = 0 ⇒ x = 5
Hence, length of the table = (5 + 4) ft = 9 ft.
Sol. Let the length and breadth of the field be (5x) metres and (3x) metres respectively.
Then, 2 (5x + 3x) = 480 ⇒ 8x = 240 ⇒ x = 30.
So, length = 150 m, breadth = 90 m.
∴ Area of the field = (150 × 90) sq. m = 13500 sq. m.
