2.	In a row of 30 girls, when Shivani was shifted to her left by 6 places, her number from the left end of the row becomes 8th. What will be the number of Urvashi from the right end of the row, if Urvashi was 4 places to right of shivani’s original position ?1. 12th2. 13th3. 14`th4. 16th
Answer» Correct Answer - Option 2 : 13th From the given information, Shivani's original position from left = New position of Shivani from left + 6 = 8 + 6 = 14th Urvashi's position from left = Shivani's original position from left + 4 = 14 + 4 = 18th Now, Total number of girls = 30 Urvashi's position from left + Urvashi's position from Right - 1 = 30 ⇒18 +Urvashi's position from Right - 1 = 30 ⇒17+Urvashi's position from Right = 30 ⇒Urvashi's position from Right = 30 - 17 ⇒Urvashi's position from Right = 13th So, Urvashi's position is 13thfrom the right end. Hence, the13this the correct answer.

In a row of 30 girls, when Shivani was shifted to her left by 6 places, her number from the left end of the row becomes 8th. What will be the number of Urvashi from the right end of the row, if Urvashi was 4 places to right of shivani’s original position ?1. 12th2. 13th3. 14`th4. 16th

Answer» Correct Answer - Option 2 : 13th

From the given information,

Shivani's original position from left = New position of Shivani from left + 6 = 8 + 6 = 14th

Urvashi's position from left = Shivani's original position from left + 4 = 14 + 4 = 18th

Now,

Total number of girls = 30

Urvashi's position from left + Urvashi's position from Right - 1 = 30

⇒18 +Urvashi's position from Right - 1 = 30

⇒17+Urvashi's position from Right = 30

⇒Urvashi's position from Right = 30 - 17

⇒Urvashi's position from Right = 13th

So, Urvashi's position is 13thfrom the right end.

Hence, the13this the correct answer.

Answer» Correct Answer - Option 1 : 14

Position of Sushil from the left = 5th

Position of Mohamed from the right = 6th

On interchanging their positions,

Position of Sushil from the right =6th

Position of Mohamed from the left =5th

and, Position of Sushil from the left after interchanging = 13th

Total number of boys in the formation =Position of Sushil from the left after interchanging +Position of Sushil from the right - 1

= 13 + 6 - 1

= 19 - 1

=18

Again,Total number of boys in the formation = 18

Position of Mohamed from the left +Position of Mohamed from the right after interchanging - 1 = 18

⇒5 +Position of Mohamed from the right after interchanging - 1 = 18

⇒4 +Position of Mohamed from the right after interchanging = 18

⇒Position of Mohamed from the right after interchanging = 18 - 4 = 14th

Hence, Mohamed is 14th from the right.

Answer» Correct Answer - Option 1 : 12

According to the given information:

Total students = 60

Let the number of girls be = x

Then, the number of boys = 2x

Now,

x + 2x = 60

3x = 60

x = 60 / 3

x = 20

Given, Reena's rank from the top = 17th

Number of boys in front of Reena = 9

Number of girls in front of Reena = 17 - 1 - 9 = 7

Thus, the number of girls after Reena = 20 - 7 - 1 = 12

Hence, the correct answer is "12".
