85 - 28 × 3 + 114 ÷ 6 = 150 ⇒ 85 - 28 + 3 × 114 ÷ 6 = 150

85 - 28 + 3 × 19 = 150 

85 + 57 - 28 = 150

142 - 28 = 150

114 ≠ 150 (LHS ≠ RHS)

• Option - (2) : - and ÷

85 - 28 × 3 + 114 ÷ 6 = 150 ⇒ 85 ÷ 28 × 3 + 114 - 6 = 150

3.03 × 3 + 114 - 6 = 150

27 + 114 - 6 = 150

141 - 6 = 150

135 ≠ 150 (LHS ≠ RHS)

• Option - (3) : ÷ and ×

85 - 28 × 3 + 114 ÷ 6 = 150 ⇒ 85 - 28 ÷ 3 + 114 × 6 = 150

Given:

Tan θ = 8/15

Formula used:

By Pythagoras theorem:

H² = P² + B²

Tan θ = P/B

Sin θ = P/H

Where, H = hypotenuse

P = perpendicular ; B = base

Calculation:

Tan θ = 8/15 = P/B

By Pythagoras theorem:

⇒ H2 = P2 + B2

⇒ H2 = 8² + 15²

⇒ H = √(64 + 225) = √289

⇒ H = 17

Now,

$√{\frac{1-\sin\theta}{1+\sin\theta}}~$

Putting the values in equation:

⇒ √[{1 - (8/17)}/{1 + (8/17)}]

⇒ √[{9/17}/{25/17}]

Given:

Cost price (C.P) = Rs.80

Marked price (M.P) = Rs.125

Discount (D)% = 40%

Concept used:

If discount is = D%

M.P : S.P = 100 : (100 - D)%

Calculation:

C.P : M.P = 80 : 125 = 16 : 25

Discount (D)% = 40%

M.P : S.P = 100 : 60 = 5 : 3 

Marked price must be same.

M.P : S.P = (5 : 3) × 5 = 25 : 15

C.P : M.P : S.P = 16 : 25 : 15

Percentage loss = {(16 - 15) × 100}/16

⇒ 100/16 = 6.25%

∴ The correct answer is 6.25%.

Shortcut TrickCalculation:

Selling price (S.P) = 125 × (100 - 40)% 

⇒ 125 × 60% = Rs.75

Gain% = {(80 - 75) × 100}/80

⇒ 50/8 = 6.25%

∴ The correct answer is 6.25%.

Given:

The height of the tree = 3.15 m

The height of the building = 11.25 m

The distance between Subhas and the tree = 7.5 m

The distance between the tree and the building = 45 m

Calculation:

Let the height from the ground at which Subhas’s eyes are situated be h.

XA = OB = PC = h

From the question:

YB = 3.15 m ; ZC = 11.25 m

AB = 7.5 m ; BC = 45 m

XO = AB = 7.5 m

OP = BC = 45 m

XP = XO + OP

⇒ XP = 7.5 m + 45 m

∴ XP = 52.5 m

Now,

OY = BY - OB

⇒ OY = 3.15 - h

PZ = ZC - PC

⇒ PZ = 11.25 - h

In ΔXPZ,

⇒ tan θ = PZ/PX

⇒ tan θ = (11.25 - h)/52.5  ----------------(1)

Similarly, in ΔXOY,

⇒ tan θ = OY/OX

⇒ tan θ = ( 3.15 - h)/7.5   ---------------(2)

From eq. (1) & (2)

⇒ (11.25 - h)/52.5 = ( 3.15 - h)/7.5

⇒ 11.25 - h = 7(3.15 - h)

⇒ 11.25 - h = 22.05 - 7h

⇒ 7h - h = 22.05 - 11.25

⇒ 6h = 10.8

⇒ h = 10.8/6

⇒ h = 1.8 m

∴ The correct answer is 1.8 m.

Shortcut Trick

For a circle with two parallel chords of lengths L₁ and L₂ at distances d₁ and d₂ from the center, the radius r satisfies: r² = d₁² + (L₁/2)² = d₂² + (L₂/2)².

Given L₁ = 10 (half = 5), d₁ = 12 ⇒ r² = 12² + 5² = 169 ⇒ r = 13 cm.

For L₂ = 24 (half = 12) ⇒ 13² = d₂² + 12² ⇒ 169 = d₂² + 144 ⇒ d₂ = 5 cm.

Since chords are on opposite sides of the center, Distance = d₁ + d₂ = 12 + 5 = 17 cm.

∴ The correct answer is 17 cm.

Alternate Method

Given:

Length of chord AB = 10 cm, Chord CD = 24 cm.

Distance of AB from center (OM) = 12 cm.

Formula Used:

The perpendicular from the center of a circle to a chord bisects the chord. In a right-angled triangle, Pythagoras theorem states: Hypotenuse² = Base² + Perpendicular².

In circle with center O, let AB and CD be the parallel chords.

OM ⊥ AB and ON ⊥ CD. Since they are on opposite sides, the distance between them is MN = OM + ON.

⇒ AM = AB ÷ 2 = 10 ÷ 2 = 5 cm.

⇒ In ΔOAM, OA² = OM² + AM²

⇒ r² = 12² + 5² = 144 + 25 = 169

⇒ r = √169 = 13 cm.

⇒ In ΔOCN, OC² = ON² + CN², where CN = CD ÷ 2 = 24 ÷ 2 = 12 cm.

⇒ 13² = ON² + 12²

⇒ 169 = ON² + 144

⇒ ON² = 169 − 144 = 25

⇒ ON = 5 cm.

⇒ Total distance MN = OM + ON = 12 + 5 = 17 cm.

∴ The correct answer is 17 cm.

Additional Information

Distance Between Parallel Chords

If chords are on the same side of the center, distance = |d₁ − d₂|. If on opposite sides, distance = d₁ + d₂.

Perpendicular Bisector Property

The perpendicular from the center to a chord always bisects it, creating two right-angled triangles with the radius as the hypotenuse.

Cos θ = B/H ; sin θ = P/H

Where, P = perpendicular ; B = Base

and H = Hypotenuse 

Calculation:

Cos θ = 39/89 = B/H

By Pythagoras theorem:

H2 = P2 + B2

⇒ (89)² = P² + (39)²

⇒ P² = 89² - 39²

⇒ P = √{(89 - 39) × (89 + 39)}

⇒ P = √(50 × 128)

⇒ P = 80

Now, Sin θ = P/H = 80/89

Cot (90 + θ) = - tan θ   

Calculation:

⇒ Tan 2θ = 1/tan θ

⇒ Tan 2θ  = cot θ 

From the above relation, we can conclude that

⇒ 2θ + θ = 90

⇒ θ = 90/3 = 30°

Cot 5θ = Cot 5 × 30

⇒ cot 150° = cot (90° + 60)

⇒ - tan 60° = - √3

∴ The correct answer is - √3.

Percentage less in weight = 25%

1000 : 750 = 4 : 3

C.P : S.P = 3 : 4

Total C.P : total S.P = 75 : 108

Gain % = {(108 - 75) × 100}/75

Radius (OP) = 1.7 cm

Concept used:

The distance of a chord from the centre cuts the chord in half and perpendicular to it.

Calculation:

OM ⊥ PQ

PM = 3/2 = 1.5 cm

Now, By Pythagoras theorem

⇒ H² = P² + B²

⇒ (1.7)² = OM² + (1.5)²

⇒ OM² = 1.7² - 1.5²

⇒ OM = √{(1.7 + 1.5)(1.7 - 1.5)}

⇒ OM = √{3.2 × 0.2} = √0.64

⇒ OM = 0.8 cm

∴ The correct answer is 0.8 cm.

Given:

Two points P and Q are 3 cm apart. These two points lie on the circumference of a circle with a radius of 1.7 cm.

Concept Used:

Use the properties of circles and right triangles to find the perpendicular distance from the center of the circle to the line segment PQ.

Formula Used:

1. Pythagorean theorem:$a^2 + b^2 = c^2$
2. The perpendicular distance from the center to the chord: $d = \sqrt{r^2 - \left(\frac{chord length}{2}\right)^2}$

Calculation:

Identify the given values:

Radius of the circle r = 1.7 cm

Length of the chord PQ = 3 cm

Calculate half of the chord length

Use the formula to find the perpendicular distance from the center to the chord:$\frac{chord length}{2} = \frac{3}{2} = 1.5 cm$

$d = \sqrt{r^2 - \left(\frac{chord length}{2}\right)^2}$ $d = \sqrt{1.7^2 - 1.5^2}$ $d = \sqrt{2.89 - 2.25}$ $d = \sqrt{0.64}$ $d = 0.8 cm$

So, the distance of the line segment PQ from the center of the circle is 0.8 cm.

Given:
