Solution of Sample Paper

Section – A

1. 20th term from the end = 1 – ( n – 1 ) d            ½

= 253 – 19 x 5           1

= 158         ½

Detailed Solution :

Given , A.P .: 3 , 8 , 13 , ……….. 253

Here , first term ( a ) = 3 , common difference ( d ) = 8 – 3 = 5 and last term ( l ) = 253           1

Then , 20th term from the end of the A.P.

= l – ( n – 1 ) d

= 253 – ( 20 – 1 ) 5

= 253 – 95

= 158               1

OR

7a7 = 11a11

⇒ 7 (a + 6d ) = 11 ( a + 10d )           1

⇒ a + 17d = 0

∴ a18 = 0           1

Detailed Solution :

Given , 7a7 = 11a11

∴ an = a + ( n – 1 ) d

Then , 7 [ a + ( 7 – 1 ) d ] = 11 [ a + ( 11 – 1 ) d ]

⇒ 7 ( a + 6d ) = 11 ( a + 10d )

⇒ 7a + 42d = 11a + 110 d

⇒ 11a – 7a = 42d – 110d

⇒ 4a = -68d

⇒ a = -17d            1

⇒ a + 17d = 0

i.e., a + ( 18 – 1 ) d = 0

Hence , a18 = 0 .           1

2. Total distance of the journey = 600 km

Let speed of fast train = x km / h ,

then speed of slow train = ( x – 10 ) km / h

According to question ,

A picture containing tableDescription automatically generated

Either , x = 50 or x = -40

∴ speed can not be negative .

So , the speed of fast train = 50 km / h ,

and the speed of slow train = 50 – 10 = 40 km / h .           1

3. Here , PQ = 6 cm , OP = OQ = 6 cm ( radii )

∴ PQ = OP = OQ

∠POQ = 60 ° ( angle of equilateral △ )              ½

∠OPT = ∠OQT = 90 ° ( radius ⊥ tangent )

∴ ∠PTQ + 90 ° + 90 ° + 60 ° = 360 ° ( angle sum property )         ½

∠PTQ = 120 °         1

4. Diameter of well = 4 m

Radius of well , r = 2 m

Depth of well , h = 21 m ,

Volume of earth dug out = πr²h

22 / 7 x 2 x 2 x 21

= 264 m³                 ½

Width of embankment = 3 m

Outer radius of ring = 2 + 3 = 5 m

Let the height of embankment be h

∴ Volume of embankment = Volume of earth dug out

∴ Height of embankment = 4 m .          1

6. Since roots of the equation x² + 4x + k = 0 are real

⇒ 16 – 4k ≥ 0

⇒ k ≤ 4             2

Detailed Solution :

Given x² + 4x + k = 0 .

Comparing the given equation with

ax² + bx + c = 0 ,

we get a = 1 , b = 4 , c = k             1

Since , given the equation has real roots

⇒ D ≥ 0

⇒ b2 – 4ac ≥ 0

⇒ 4² – 4 × 1 × k ≥ 0

⇒ 4k ≤ 16

⇒ k ≤ 4         1

OR

Given : 2x² – 4x + 3 = 0

On comparing above with ax² + bx + c = 0 ,

we get , a = 2 , b = -4 , c = 3         1

Now , D = b² – 4ac

So , D = ( -4 ) ² – 4 ( 2 ) × ( 3 )

= -8 < 0 or ( -ve )

Hence , the given equation has no real roots .          1

Detailed Solution :

Given , Side of cube = 6 cm

Diameter of hemisphere = 3.5 cm

Radius of hemisphere = 3.5 / 2         ½

Total surface area of cube = 6a²

= 6 x ( 6 ) ² = 216 cm²                  ½

Total surface area of solid = TSA of cube – Area of circle + CSA of hemisphere .

13. ( i ) Clearly , distance covered by the artist is equal to the length of the rope AC .

Let AB be the vertical pole of height 12 m .

It is given that ∠ACB = 30 °

Thus , in right – angled triangle ABC ,         1

sin 30 ° = AB / AC
