Correct Answer: 16

Solution : The given figure can be labelled as shown below –

Now, in the above figure, there are 16 triangles. They are ABH, BCD, DEF, FGH, LHI, IBJ, JKD, LKF, LMK, LMI, JKM, MIJ, JKL, IJL, IJK, IKL.

Hence, the second option is correct.

Correct Answer: 1 : 2

Solution : Given: Radius of bigger sphere = 4 cm
The radius of a smaller sphere = 2 cm
Let the radius of the bigger sphere be $R$ and smaller be $r$.
According to the question,
Number of spheres formed = $\frac{\text{Volume of bigger sphere}}{\text{Volume of smaller spheres}}$
= $\frac{\frac{4}{3}\pi R^3}{\frac{4}{3}\pi r^3}$
= $\frac{R^3}{r^3}$
= $\frac{4^3}{2^3}$
= 8
Now, the surface area of the original sphere = $4\pi R^2$ = $4\pi (4)^2$ = $64\pi$
And sum of surface area of small spheres = $8 × 4\pi (2)^2$ = $128\pi$
The required ratio = $64\pi : 128\pi= 1 : 2$
Hence, the correct answer is 1 : 2.

Correct Answer: Legal environment

Solution : Every business enterprise must follow the law of the land. As a result, it is critical for every business to understand the rules and regulations established by the government. The Trade Union Act of 1926' is an example of a legal environment in the preceding case.
Hence, option 1 is the correct answer.

Correct Answer: 5 and 9

Solution : Given:
5 – 6 ÷ 3 × 9 + 1 = 0

Let's check the options –
First option: 1 and 0
5 – 6 ÷ 3 × 9 + 1 = 0
On interchanging the numbers, we get –
⇒ 5 – 6 ÷ 3 × 9 + 0 = 1
⇒ 5 – 2 × 9 + 0 = 1
⇒ 5 – 18 + 0 = 1
⇒ –13 ≠ 1
Second option: 6 and 9
5 – 6 ÷ 3 × 9 + 1 = 0
On interchanging the numbers, we get –
⇒ 5 – 9 ÷ 3 × 6 + 1 = 0
⇒ 5 – 3 × 6 + 1 = 0
⇒ 5 – 18 + 1 = 0
⇒ –12 ≠ 0
Third option: 5 and 9
5 – 6 ÷ 3 × 9 + 1 = 0
On interchanging the numbers, we get –
⇒ 9 – 6 ÷ 3 × 5 + 1 = 0
⇒ 9 – 2 × 5 + 1 = 0
⇒ 9 – 10 + 1 = 0
⇒ 0
Fourth option: 6 and 3
5 – 6 ÷ 3 × 9 + 1 = 0
On interchanging the numbers, we get –
⇒ 5 – 3 ÷ 6 × 9 + 1 = 0
⇒ 5 – 0.5 × 9 + 1 = 0
⇒ 5 – 4.5 + 1 = 0
⇒ 1.5 ≠ 0

Here, only the third option satisfies the equation. Hence, the third option is correct.

Correct Answer: Cast iron

Solution : The correct option is Cast iron.

Cast iron is an alloy with a carbon content of 2–5%. Hard steel is an iron alloy with a relatively low carbon content. Hence, a minor amount of carbon is added to boost its strength. Steel is also ductile and flexible. The iron alloy known as wrought iron has a low carbon content.

Correct Answer: Debited by Rs 13,687

Solution : Answer = Debited by Rs 13,687

Total Profit of Last 3 years = 2,19000
X's Share of Profit = 2,19000 × 4/8

                            = 109500
X's Share of Goodwill = 109500 × 50 % = 54750
G. Ratio = NR - OR
Y = 1/2 - 3/8 = 4.3/8 = 1/8

Z = 1/2 - 1/8 = 4-1/8 = 3/8
G. Ratio = 1:3

Y's Capital A/C Dr 13687
Z's Capital A/C Dr 41063
To X's Capital A/C 54750
(G. Ratio = 1:3)
Hence, the correct option is 1.

Correct Answer: Addressing

Solution : The second option is correct.

In this context, addressing means dealing with or taking the necessary measures to resolve.

The sentence implies that in order to tackle or confront the threats facing elephants, there needs to be a desire or determination from the public and political entities.

Correct Answer: CHEJ

Solution : Given:
AFCH, ?, EJGL, GLIN, INKP

In the above-given series, add 2 to the place value of each letter of the previous term to get the next term.
AFCH→A + 2 = C, F + 2 = H, C + 2 = E, H + 2 = J
CHEJ→C + 2 = E, H + 2 = J, E + 2 = G, J + 2 = L
EJGL→E + 2 = G; J + 2 = L, G + 2 = I, L + 2 = N
GLIN→G + 2 = I, L + 2 = N, I + 2 = K, N + 2 = P

So, the missing term of the series is CHEJ. Hence, the third option is correct.
