Raghav spent one - third of his money on a book. He spent three - fourth of the remainder on a pen. If the pen costs six rupees more than the books, then the total money he spent is ______ rupees.need the explanation !! |
|
Answer» Answer: 300 Rs Step-by-step explanation: we will USE them method of assumption here. First CHECK the data to ease up the calculation.1/3 and 1/4 is given , LCM of 3 & 4 is 12. So LET us assume that the Total Money he has is 12units spend 1/3 on book =1/3*12=4 units this means he spent 4 UNIT on book. Now he is LEFT with 8 units ATQ he spends 3/4 of the remainder on a pen (this statement has the main logic) it 8*3/4=6units on pen this means out of 12 units, he spend 6 units on pend & 4 units on book. NOW ATQ the difference b/w spending of book and pen is 60RS but according to our assumption it is 6units-4units=2units ATQ 2units is equal to 60rs according to statement 2units=60 1 unit=30 Total money He Spent= 10 units 10 units= 300Rs |

In triangle ABC ,D and E are points on AB and AC such that DE is parallel to BC. If AD = 4cm .DC =8cm and AE =4.5 cm ,find the length of CE8cm9cm4.5cm4cm |
|
Answer» Step-by-step explanation: Answer. Step-by-step explanation: GIVEN: In Δ ABC, D and E are points on AB and AC , DE || BC and AD = 2.4 cm, AE = 3.2 cm, DE = 2 cm and BE = 5 cm. Hence,BD = 3.6 cm and CE = 4.8 cm. OR 10th Maths Triangles Basic PROPORTIONALITY Theorem (Thales Theorem) In ABC, D and E are points... MATHS In △ABC, D and E are points on the sides AB and AC respectively such that DE || BC. If AD = 6 cm, DB = 9 cm and AE = 8 cm, find AC. HARD Share Study later ANSWER The basic proportionality theorem STATES that if a line is drawn parallel to one side of a triangle and it intersects the other two sides at two distinct points then it divides the two sides in the same ratio. It is given that AD=6 cm, DB=9 cm and AE=8 cm. Using the basic proportionality theorem, we have ABAD=ACAE=BCDE⇒ABAD=ACAE⇒156=AC8⇒6AC=15×8⇒6AC=120⇒AC=6120=20 Hence, AC=20 cm. |

Is- 9. A right circular cylinder and a sphere have the same volume and same radius. The ratioof the areas of their curved surfaces isIf the radius of a sphere is doubled, then the percentage increase in the surface areaCLS |
|
Answer» Step-by-step explanation: Volume of sphere = (4/3)(pi)*R^3. Volume of cylinder= (pi)*r^2*H. The volumes of both solids being equal (4/3)(pi)*r^3 = (pi)*r^2*h, or (4/3)*r = h. Surface AREA of sphere = 4(pi)r^2 = (pi)[4r^2] …(1) CURVED surface area of cylinder= 2(pi)rh = (pi)2r(4/3)r …(2) Ratio of curved surface of cylinder to the surface area of the sphere = (pi)2r(4/3)r / (pi)[4r^2] = (8/3)/4 = 2/3. |
