By checking Option A,

18×20÷2+6-4=32

After changing the symbols,

18×20÷2-6+4=32

Applying BODMAS we get,

=18×10-2

=180-2=178

Therefore, 18×20÷2+6-4=32 is not the correct equation.

By checking Option B,

18×20÷2+6-4=32

After changing the symbols,

18-20÷2+6×4=32

Applying BODMAS we get,

=18-10+24

=8+24

=32

Therefore, 18×20÷2+6-4=32 is the correct equation.

By checking Option C,

18×20÷2+6-4=32

After changing the symbols,

18×20+2÷6-4=32

Applying BODMAS we get,

=360+2÷6-4

Here, result will appear in fraction.

Therefore, 18×20÷2+6-4=32 is not the correct equation.

By checking Option D,

18×20÷2+6-4=32

After changing the symbols,

18÷20×2+6-4=32

Applying BODMAS we get,

=18÷20×2+6-4

Here, result will appear in fraction.

Therefore, 18×20÷2+6-4=32 is not the correct equation.

Hence, Option B is the correct answer.

Pattern is-

4 × 2 + 2 = 10

10 × 3 − 3 = 27

27 × 5 + 5 = 140

140 × 7 − 7 = 973

Hence, option B is the correct answer.

The mirror image will be:
 
Hence, option D is the correct answer.

We know, Sum of Angles of triangle = 180°
so, ∠ BAC = 180° - (72 + 44) = 64°

Now, from theorem we know
∠BEC = ∠A/2 = 32°

Alternate Approach:

Since BE and CE are angle bisectors.
∠CBE = ∠CBA/2 = 72°/2 = 36°
and ∠BCE = ∠BCA + ∠ACD/2 = 44° + (180°−44°)/2
∠BCE = 112°
 
Now, In triangle BCE, 
∠BEC = 180°−36°−112° = 32°

A.T.Q.

∠QPR = 30°
⇒ 
⇒ 
⇒ d = 270×1.732 = 467.64
= 467.55 (approx.)

If two successive discounts are d₁% and d₂%, then,
Net discount% =  

Hence, net discount% = 20 + 35 –

= (55 – 7)%

= 48 %

Mahad Satyagrah of 1927 was led under the leadership of BR Ambedkar.

• It was the first collective mass protest of untouchables and is also the landmark satyagrah in establishing the leadership of BR Ambedkar at national level.
