Correct Answer: 15

Solution : Ratio of Two numbers = 4 : 3
HCF × LCM = 2700
Product of two numbers = Product of their HCF and LCM
Let the numbers be $4x$ and $3x$ respectively
⇒ $x × 12x = 2700$
⇒ $12x^2 = 2700$
⇒ $x^2 =

K, I, G, E, C, ?

Subtract 2 from the positional value of the letter, to obtain the required missing letter in the series –
K → K – 2 = I,
I → I – 2 = G,
G → G – 2

Correct Answer: equestrian rider

Fouaad Mirza is an accomplished Indian equestrian. His notable achievements include winning silver medals in individual and team eventing at the 2018 Asian Games, making him the first Indian in over three decades to secure an

Correct Answer: 61.2

Solution : Given: A train of length 180 m takes 40 seconds to cross a tunnel of length 500 m.
Use the formula, $\text{Speed}=\frac{\text{Distance}}{\text{Time}}$.
Train’s speed = $\frac{180+500}{40}=\frac{680}{40}$ m/s
Convert m/s into km/h by multiplying with $\frac{18}{5}$,
$\frac{680}{40}$ m/s = $\frac{680}{40}\times \frac{18}{5}$ km/hr = 61.2 km/hr
Hence,

Solution : As per the given graph,
The number of workers whose age is 28 years or more but less than 40 years = 90 + 85 + 70 = 245
The number of workers whose age is 40 years or more but less than

Correct Answer: 60

Solution : The ratio of the two numbers is 4 : 5.
Let the numbers be 4$x$, 5$x$.
Their HCF = $x$ as 4, 5 are coprime.
So, $x$ = 3
Numbers are 4 × 3 = 12, 5 × 3 = 15
We know the product
