Explanation

Let "x" be the number.

Three-fourths of the number is (3/4)x.

When we multiply the number by three-fourths of itself,

we get: x * (3/4)x = 10700.

This simplifies to (3/4)x² = 10700.

Solving for x, we get x = 70. 

Explanation

 The result of 50−15.5 is 34.5.

Explanation

Given:

Time taken by A and B to complete the work = 12 days

Time taken by B and C to complete the work = 8 days

Time taken by C and A to complete the work = 6  days

Formulae used:

Time = Total work / Efficiency

Calculation:

Let us assume the total work is 1 unit.

⇒ A and B complete 1 unit work in 12 days → (A and B)'s 1 day's work = 1/12​

⇒ B and C complete 1 unit work in 8 days → (B and C)'s 1 day's work = 1/8​

⇒ A and C complete 1 unit work in 6 days → (A and C)'s 1 day's work = 1/6​

Adding everyone's 1 day's work:

$\Rightarrow 2(A+B+C)=(1/12+(1/8)+(1/6)$

⇒A+B+C=9/48​

= A, B, and C's 1 day's work = 9/48

⇒ B's 1 day's work = $(A+B+C)-(A+C)$

⇒ B's 1 day's work =(9/48)−(1/6) = 9-8 x/48 = 1/ 48 ​

​

⇒ B completes 1/48​ of the work in 1 day.

Therefore, B alone will take 48 days to complete the work.

Explanation

Given:

A sphere of radius 3 cm

Formula Used:

Total surface area of sphere = $4\times 22/7\times r^2$; where r = radius of sphere

Calculation:

⇒ Total surface area of sphere = $4\times 22/7\times 3^2$

⇒ Total surface area of sphere = $\frac{792}{7}=113.4{\text{cm}}^2\approx 113{\text{cm}}^2$

∴ required Total surface area of sphere = 113cm2
