4.	A is twice as good as workman b and together they finish a piece of work in 14 days the number of days taken by a alone to finish work is in how many days
Answer» Let B FINISHES WORK in = x days A will finish the work in = x/2 days 1 day of work DONE by both together is 2/x + 1/x = 1/14 3/x = 1/14 x = 42 So B will complete work in 42 days And A will complete in 21 days

4.

A is twice as good as workman b and together they finish a piece of work in 14 days the number of days taken by a alone to finish work is in how many days

Answer»

Let B FINISHES WORK in = x days

A will finish the work in = x/2 days

1 day of work DONE by both together is

2/x + 1/x = 1/14

3/x = 1/14

x = 42

So B will complete work in 42 days

And A will complete in 21 days

7.	Height of a cylindrical drum is 56 cm. Find the radius of the drum if the capacity of that drum is 70.4 litre.(π = 22/7)
Answer» SOLUTION :- Height of the cylindrical drum = 56 cm Capacity of the cylindrical drum = 70.4 litres We know that, 1 LITRE = 1000 cu cm So, volume of the cylindrical drum = 70.41000 = 70400 cu cm Volume of cylindrical drum = πr²h ⇒ 70400 = 22/7r²56 ⇒ r² = (704007)/(22*56) ⇒ r² = 492800/1232 ⇒ r² = 400 ⇒ r = √400 ⇒ r = 20 cm So, radius of the cylindrical drum is 20 cm Answer.

7.

Height of a cylindrical drum is 56 cm. Find the radius of the drum if the capacity of that drum is 70.4 litre.(π = 22/7)

Answer»

SOLUTION :-

Height of the cylindrical drum = 56 cm

Capacity of the cylindrical drum = 70.4 litres

We know that,

1 LITRE = 1000 cu cm

So, volume of the cylindrical drum = 70.4*1000 = 70400 cu cm

Volume of cylindrical drum = πr²h

⇒ 70400 = 22/7*r²*56

⇒ r² = (70400*7)/(22*56)

⇒ r² = 492800/1232

⇒ r² = 400

⇒ r = √400

⇒ r = 20 cm

So, radius of the cylindrical drum is 20 cm

10.	Seg AD and seg BE are medians of ???? ABC and point G is the centroid. If l(AG) = 5 cm, find l(GD). If l(GE) = 2 cm, find l(BE).
Answer» Did you know about one THING ? $\bf{Centroid}$ divides MEDIAN in 2 :1 ratio. in simple way, if ∆ABC is a TRIANGLE where AD and BE are medians . both AD and BE intersect at a POINT G , it is not other than Centroid. now, from above concept . G divides AD in 2 : 1 ratio. e.g., AG/GD = 2/1 Given, AG = 5 cm then, GD = AG/2 = 5cm/2 = 2.5 cm hence, length of GD = 2.5 cm similarly, G divides BE in 2 : 1 ratio e.g., BG/GE = 2/1 given, GE = 2 cm then, BG = 2 × GE = 2 × 2 = 4cm now, length of BE = BG + GE = 4cm + 2cm length of BE = 6cm

21.	the length of the sides of a triangle form a G.P. If the perimeter of the triangle is 37cm and the shortest side is of length 9 cm, find the length of the other two sides?
Answer» The 3 sides of the triangle are a, ar and ar^2 and while a = 9 the sum is 37 cm. S3 = a(R^n-1)/(r-1), or 37 = 9(r^3–1)/(r-1) = 9(1+r+r^2) = 9 +9R+ 9 r^2, or 28=9r+9r^2, or 9r^2+9r-28=0 9r^2+21r-12r-28 = 0 3r(3r+7) - 4(3r+7) = 0 (3r-4)(3r+7) = 0 Or r = 4/3 or -7/3.

Round each factor with more than one digit to the nearest ten (a).78*8

Answer»

Answer:

Round off 6.24 to the nearest TENS is 6.2.

Step-by-step explanation:

GIVEN : Number $0.78\times8$

To find : Round the given digit to the nearest ten

Solution :

First we multiply the given digit

$0.78\times8$

$=6.24$

Round off to the nearest ten MEANS

If the hundred digit is more than 5 i.e, 5,6,7,8,9 then it round to up or additional ONE unit.

If the hundred digit is less than 5 i.e, 1,2,3,4 then it round to down or remain same.

In 6.24 the place of hundredth is 4 less than 5 so, it round to down or remain same.

Round off 6.24 to the nearest tens is 6.2.

Answer»

A lends money to B= 2500

A lends money to C =?

Rate of INTEREST= 7%

time = 4 YEARS

Total money of interest after 4 years B+C= 1120

ANSWER:

step 1: calculate the amount of A lending money to B
