Given that the ratio of the sides of triangles MNO and XYZ is 9 : 4.
$ \frac{\text{Area of $\triangle$XYZ}}{\text{Area of $ \triangle  $MNO}}=(\frac{9}{4})^2

Correct Answer: 4

Solution :
Given: The radius of a circle OQ is 3 cm and 'O' is its centre.
P at a distance of 5 cm from 'O'.
If the tangent from P touches the circle at Q. Then, $\triangle$ PQO is a right-angled triangle and the length of

Correct Answer: MVGIUVSU

Solution : Given:
LOVING is coded as HOJWPM, and EAGLE is coded as FMHBF.

Reverse the letters of LOVING, and then add 1 to the place value of each letter, to obtain the required code –
Reverse the letters of LOVING→GNIVOL
Now, add 1 to the reversed

Correct Answer: 300%

Solution : Given, 30% of P = 15% of Q ⇒ ($\frac{30}{100}$)P = ($\frac{15}{100}$)Q ⇒ P = ($\frac{1}{2}$)Q
also, 20% of Q = 10% of R ⇒ ($\frac{20}{100}$)Q = ($\frac{10}{100}$)R ⇒ Q = ($\frac{1}{2}$)R
from the above two relations, we get,
P = ($\frac{1}{4}$)R
⇒ R =

Correct Answer: SM

Solution : Given:
JJ : MG :: PP : ?

Like, JJ→J + 3 = M; J – 3 = G→MG
Similarly, PP→P + 3 = S; P – 3 = M→SM

So, SM is the required letter cluster of the given pair. Hence, the third option

Correct Answer: 90 km/h

Solution : Speed of train = 80 km/h
Total distance covered by the train = 80 × 4.5 = 360 km
Therefore, the speed required to cover the same distance in 4 hours:
Speed = $\frac{\text{Distance}}{\text{Time}}$
= $\frac{360}{4}$ = 90 km/h
Hence, the correct answer is

Correct Answer: AUO

Solution : Given:
AEI : OUA :: IEA : ?

Each letter of AEI is related to an individual letter.
A→O; E→U; I→A
Similarly, for AEI –
I→A; E→U; A→O

So, IEA is related to AUO. Hence, the second option is correct.
