8 men can do the job in 12 days

So, 6 men can do te job in 12×8/6 = 16 days

Increase percentage in number of days = (16 - 12) / 12 × 100% = 33.33%

Answer: Option D

Explanation:

x এবং y এর গড় অর্থাৎ (x + y)/2 এর মান বের করতে হবে ।

এখন, 8x + 8y = 64

= > 8 (x + y) = 64

= > 8(x + y)/16 = 64/16 [ 16 দ্বারা উভয় পক্ষকে ভাগ করে ]

= > (x + y)/2 = 4

Answer: Option D

Explanation:

we have (a^{3} + b^{3} + c^{3} - 3 abc) = (a + b + c) \times (a^{2} + b^{2} + c^{2} - ab - bc - ac) when a + b + c = 0 [given] then, a^{3} + b^{3} + c^{3} = 3 abc \Rightarrow \frac{a^{3}}{abc} + \frac{b^{3}}{abc} + \frac{c^{3}}{abc} = 3 \Rightarrow \frac{a^{2}}{bc} + \frac{b^{2}}{ac} + \frac{c^{2}}{ab} = 3
