Explanation

The quadratic equation whose roots are reciprocal of:

2x2 + 5x + 3 = 0 can be obtained by replacing x by 1/x.

Hence, 2(1/x)2 + 5(1/x) + 3 = 0

=> 3x^2 + 5x + 2 = 0

Explanation

A man sold two scooters for 24000 each.

Find the cost price of one scooter at gain of 20% :-

C.P = (S.P × 100)/(100 + gain)

= (24000 × 100)/(100 + 20)

= 2400000/120

= 20000

Explanation

We are given:

• PQS, QRT, RSU, STV, and need to find the next term in the sequence.

The pattern follows the sequence of consecutive letters:

• First letters: P, Q, R, S, T (increasing by 1)
• Second letters: Q, R, S, T, U (increasing by 1)
• Third letters: S, T, U, V (increasing by 1)

The next set of letters should be T, U, W.

(A) TUW

Explanation

By Decoding the given Sequence in the way $A\to 1;B\to 2;....Z\to 26$

$A,D,H,M,S\to 1,4,8,13,19$

The difference between two successive numbers is increasing by '1' starting from with '3'

$1+3=4$

$4+4=8$

$8+5=13$

$13+6=19$

$19+7=26$

Hence according to decoded language the next number is '26' i.e $Z$
