A)
14 cm
B)
10 cm
C)
7 cm
D)
6 cm

A)
1 km
B)

A 13 m long ladder reaches a window of a building 12 m above the ground, then the distance of the foot of the ladder from the building is -
A)
11 m
B)
10 m
C)
5 m
D)
4 m
The ladder, the wall, and the ground form a right triangle. Here, the ladder is the hypotenuse = 13 m and the height reached on the building = 12 m. Using Pythagoras theorem: foot distance = √(13² - 12²) = √(169 - 144) = √25 = 5 m. So the correct answer is 5 m, which corresponds to option (c).

If the circumference of a circle is 22 cm, then the diameter of the circle is -
A)
3.5 cm
B)
7 cm
C)
14 cm
D)
15 cm
The circumference of a circle is given by C = πd. Here, C = 22 cm. So, d = 22/π. Using π = 22/7, d = 22 ÷ (22/7) = 7 cm. Therefore, the correct answer is (b) 7 cm. The other options do not satisfy the circumference formula.

The sum of the first 10 terms of the AP: 9, 7, 5, 3 ........ is -
A)
0
B)
144
C)
- 144
D)
- 441
This is an arithmetic progression with first term a = 9 and common difference d = 7 - 9 = -2. The sum of first n terms is S_n = n/2 [2a + (n - 1)d]. For n = 10, S_10 = 10/2 [2(9) + 9(-2)] = 5 [18 - 18] = 0. So the correct answer is 0. The other options do not match the computed sum.

The telephone was invented by Alexander Graham Bell in 1876, which falls in the 1870s decade. So option (c) is correct. The other options are incorrect because the telephone was not invented in the 1850s, 1860s, or 1880s.

A bus runs at a speed of 72 km/hr. Distance covered in 1 second is -
A)
10 m
B)
20 m
C)
30 m
D)
36 m
Convert 72 km/hr to m/s: 72 × 1000 / 3600 = 20 m/s. So in 1 second, the bus covers 20 meters. However, since the options given do not include 20 m except option (b), the correct option is actually (b).

A man can do a piece of work in 6 days which he can complete in 4 days when his friend helps him. His friend can complete the work alone in -
A)
12 days
B)
24 days
C)
6 days
D)
4 days
Let the man's 1-day work be 1/6. With his friend's help, their combined 1-day work is 1/4. So the friend's 1-day work = 1/4 - 1/6 = (3 - 2)/12 = 1/12. Therefore, the friend alone can finish the work in 12 days? Wait carefully: 1/4 - 1/6 = 1/12, so the friend takes 12 days. However, this does not match the options. Rechecking the standard interpretation: if the man can do it in 6 days and with friend in 4 days, then friend's rate is 1/12, so time is 12 days. Since 12 is not among the options, the question/options appear inconsistent. Hence it cannot be solved with the given options.
