57. (C) Area of tank = 180 × 120 = 21600 m2
Area of land (without tank) = 40000 m2
Area of field = 40000 + 216000

So, x = 12 or – 10

69. (B) Distance between two town is = 800 kms
Length of the shadow of tree (BC) = 16 m Related speed = (30 + 50) km/hr
So, height of tree (AB) = tan 60° × 16 = 80 km/hr

Radius of sphere = a units
Length of cube = 2a units So, required distance = 30 × 10 = 300 kms
70. (C) Volume of wall = 18225 m3

BAC = ABC = 38°
ACB = 180° – 2 × 38° = 104°
ACD = 180° – BCA = 180° – 140°

In ACD
AD = CD 12
So, work done by (A + B + C) = = 6 units
ACD = DAC = 76° 2
D = 180° – 2 × 76° = 28° Work done by (B + C) = 3 units
66. (A) Quantity of mixture = 1kg So, work done by A = (6 – 3) = 3 units
ATQ, 360
So, time taken by A alone = = 20 days

Explanation
151. (B) Use 'other' after 'any'.
152. (C) Replace 'was' with 'were'. The subject of the sentence is plural (A loaf of bread and bottles).
Therefore, the verb must be plural.
153. (C) No error. The sentence is correct.
154. (D) Use 'its' in place of 'their'. A singular pronoun adjective (its, not theirs) must be used to
refer to a collective noun (company) when the members of the collective noun are
considered a unit.
155. (D) Use 'seems'. Collective nouns, as well as noun phrases denoing a fixed quantity, frequently
take a singular verb because the group or quantity is usually regarded as a unit.
