Correct answer is C
Total Cost Price = N(250,000 + 70,000)
= N 320,000
Selling Price = N 400,000(Given)
Gain = Selling Price - Cost Price
= 400,000 - 320,000
= 80,000
% gain = \(\frac{\text{Gain}}{\text{Cost Price}}\) × 100
= \(\frac{80,000}{320,000}\) × 100
Gain % = 25%

Correct answer is D
by method of long division, we get the answer.
40o
55o
50o
60o
Correct answer is A
Sum of angle at a point = 360o
2x + 3x + 4x = 360
9x = 360
x = \(\frac{360}{9}\)
x = 40o
three times as much
the same
twice as much
half as much
Correct answer is C
Let the speed of the 1st trip be x miles/hr
and the speed of the 2nd trip be 3x miles/hr
Speed = distance/time
∴ Time taken to cover a distance of 50 miles on the 1st trip
= \(\frac{50}{xhr}\)
time taken to cover a distance of 300 miles on the next trip
= \(\frac{300}{3xhr}\)
= \(\frac{100}{xhr}\)
∴the new time compared with the old time is twice as much
Simplify 4\(\sqrt{27}\) + 5\(\sqrt{12}\) − 3\(\sqrt{75}\)
7
− 7
− 7\(\sqrt{3}\)
7\(\sqrt{3}\)
Correct answer is D
4\(\sqrt{27}\) + 5\(\sqrt{12}\) − 3\(\sqrt{75}\)
= 4\(\sqrt{3}\) × 9 + 5\(\sqrt{3}\) × 4 − 3\(\sqrt{3}\) × 25
= 4 × 3\(\sqrt{3}\) + 5 × 2\(\sqrt{3}\) − 3 × 5\(\sqrt{3}\)
= 12\(\sqrt{3}\) + 10\(\sqrt{3}\) − 15\(\sqrt{3}\)
= (12 + 10 − 15)\(\sqrt{3}\)
= 7\(\sqrt{3}\)
