2 2 KOH (aq) +2 HNO3(aq)→2 KNO3 (aq) + 2 H2O (1)

2 KOH (1) + 2 ΗΝΟ3 (1)→ 2 KNO3 (1) + +2H2O (1 (1)

2 KOH (aq) + 2 HNO3 (1)→2 KNO3 (aq) + 2 H2O (aq)

(1) All the resistors are connected between two given points.

(ii) The equivalent resistance of the circuit is more than the individual resistance.

(iii) The potential difference across each resistor is same.

Both Statements are correct. Statement I is correct explanation of Statement II.

Both statements are correct. Statement II is correct explanation of Statement I.

Statement I: Carbon has the unique ability to form bonds with other atoms of carbon, giving rise to large molecules.

 Statement II: This property is called catenation.

A alone complete a work =4 days
B alone complete a work =6 days
LCM of these two is the work ie =12
efficiency of A=12/4=3
efficiency of B = 12/6=2
A and B are work together the one day work is 5
if C is included the work they will complete the work in 2 days so the efficiency of C is
2 days=12/efficiency of (A+B+C)
2=12/(5+C)
1=6/(5+C)
(5+C)=6
C=1

so the ratio of efficiency of A:B:C = 3:2:1
the share of C=600*(1/6)=100

sum of ages mother son daughter =70
son age =A
mother age = 3A
daughter age = A+5

A+3A+A+5=70
5A=65
A=65/5
A=13

mother age = 13*3=39

in 2018 = 35
in 2020 = 55

percentage increase =(55-35)/35
=20/35=0.57=57%

A-2=Y
L-2=J
G-2=E
30+32=62

the numbers difference is 4,8,16,32...

Rani age =R
Sister age =S
S=4+R
28=4+R
R=24

logic is 2nd number = (square of 1st number) + (half of 1st number)
(18 x 18)+(18/2)=324+9=333

NOPQR

The sum of the measures of a pair of interior angles on the same side of the transversal is 180°

The sum of the measures of a pair of alternate interior angles is 180°

The sum of the measures of a pair of corresponding angles is 180°

The sum of the measures of a pair of vertically opposite angles is 180°

Number of computers sold in 2017=60000
Number of computers sold in 2021=40000
difference between these two=60000-40000=20000
