- 30, 19
- 29, 18
- 28, 17

Answer: Option D.

x − y = 11, x + y = 5 × 9 x − y = 11, x + y = 45, y = 17, x = 28**How many numbers between 1 and 100 are divisible by 7?**- 9
- 11

- 14

Answer: Option D.

No. of divisible by 7 7, 14 --------- 98, n = a + (N - 1)d

98 = 7 + (N - 1) 7, 98 = 7 + 7N - 7

98/7= N = 14

So, the correct answer is option D.**A cyclic quadrilateral ABCD is such that AB = BC, AD = DC, AC is perpendicular to BD and ∠CAD = θ, then find the ∠ABC.**- θ
- θ/2
- 2θ
- 3θ

Answer: Option C

∠B + ∠D = 180° ∠A + ∠C = 180° ∠BAC = ∠BCA ∠DAC = ∠DCA ∴∠DAB = ∠DCB = 90° ∠DAC = θ

∴∠ADE = 90° - θ = ∠CDE ∴ ∠ABC = 180° – 2(90° - θ) = 2θ**How many integers are there between 300 and 600 that are divisible by 9?**- 33
- 31
- 28
- 25

Answer: Option A.

The sequence is 306… 594

594=306+ (n-1)9⇒288= (n-1)9⇒n=33**10. What will be the ratio of petrol and kerosene in the final solution formed by mixing petrol and kerosene that are present in three identical vessels in the ratio 4:1,5:2 and 6:1 respectively?**- 166 : 22
- 83 : 22
- 83 : 44
- 78 : 55
- None of these

Answer: Option B.

Three identical vessels in the ratio 4:1, 5:2 and 6 :1 respectively.

Petrol : kerosene

(4 : 1 = 5)7

(5 : 2 = 7)5

(6 : 1 = 7)5

28 : 7 = 35

25 : 10 = 35

30 : 5 = 35

83 : 22
