Class 8 Cryptarithm doubt (See pic). Explain how digit O can take value 2 or 4.

Answer»

Step-by-step EXPLANATION:

ACCORDING to 2*ON=GO

ON=GO/2

GO are 2 digit no max=99

so ON value max=49

therefore O=4

it means O is even number

second O can be 2 because

lowest even number 2

when we take O=2

then we get an even number on right side on GO 49÷2= 29

2*29=58( GO=58 SUPPOSE means O is even number (8)

42 37 17? 11 84 13? 74 93 ?

Answer»

Answer:

Step-by-step explanation:

The missing NUMBER of the SERIES is 46.

Step by step explanation :

Hey Mate,

Given Series : 42, 17, 37 and 11, 13,84 and 74, X, 93

#1

Take 42 and 37

Multiple 2 with 3 = 3×2 = 6

Now Sum 7 and 4 = 7 + 4 = 11

Add both the VALUE = 6 + 11 = 17

#2

Take 11 and 84

Multiple 1 with 8 = 1 × 8 = 8

Now Sum 1 and 4 = 1 + 4 = 5

Add both the value = 8 + 5 = 13

#3

Take 74 and 93

Multiple 4 with 9 = 4 × 9 = 36

Now Sum 7 and 3 = 7 + 3 = 10

Add both the value = 36 + 10 = 46

So,

The missing number of the series is 46.

The sum of the two digits number is 15. If the new number formed by reversing the digits is less than the original number by 27 find the original two digit number

Answer»

Step-by-step explanation:

let the tens digit be ' a ' and the ones digit be 'b'

a + b = 15 ( given ) - A

(10*a + b ) - 27 = 10*b + a

implies,

9A - 9b = 27. - B

by 9A + B we get

18A = 135 + 27

so we get,

a = 9

b = 6

so the NUMBERS are 96 and 69

शांति स्वीट स्टाल अपनी मिठाइयों को पैक करने के लिए गत्ते के डिब्बे बनाने का ऑर्डर दे रहा था। दो मापों के डिब्बों की आवश्यकता थी। बड़े डिब्बों की माप 25 cm x 20 cm x5 cm और छोटे डिब्बों की माप 15 cm x 12 cm x5 cm थीं। सभी प्रकार की अतिव्यापिकता (overlaps) के लिए कुल पृष्ठीय क्षेत्रफल के 5% के बराबर अतिरिक्त गत्ता लगेगा। यदि गत्ते की लागत रु 4 प्रति 1000 है, तो प्रत्येक प्रकार के 250 डिब्बे बनवाने की कितनी लागत आएगी?

Answer»

Answer:

प्रत्येक प्रकार के 250 डिब्बे बनवाने के लिए ₹ 2184 की लागत आएगी।

Step-by-step explanation:

दिया है :  

बड़े डिब्बे की विमाएं l = 25 सेमी  , b = 20 सेमी, h = 15 सेमी

बड़े आकार के डिब्बे का संपूर्ण पृष्ठीय क्षेत्रफल = 2(lb + bh + lh)

= 2(25 × 20 + 20 × 5 + 25 × 5)

= 2(500 + 100 + 125)

= 2 × 725

= 1450 सेमी²

बड़े आकार के डिब्बे का संपूर्ण पृष्ठीय क्षेत्रफल  = 1450 सेमी²

छोटे डिब्बे की विमाएं l = 15 सेमी  , b = 12 सेमी, h = 5 सेमी

छोटे आकार के डिब्बे का संपूर्ण पृष्ठीय क्षेत्रफल = 2(lb + bh + lh)

= 2(15×12 + 12×5 + 15×5)

= 2 (180 + 60 + 75)

= 2 × 315

= 630 सेमी²

छोटे आकार के डिब्बे का संपूर्ण पृष्ठीय क्षेत्रफल = 630 सेमी²

सभी अतिव्यापिकता के लिए छेत्रफल = 5% (1450 + 630)

= 5/100 × 2080

= 104 सेमी²

दोनों डिब्बों का तथा अतिव्यापिकता का संपूर्ण पृष्ठीय क्षेत्रफल = (1450 + 630 + 104) = 2184 सेमी²

250 डिब्बों के लिए संपूर्ण पृष्ठीय क्षेत्रफल = (2184 × 250) सेमी²  

∵ 1000 सेमी² के लिए गत्ते का व्यय = ₹ 4  

1 सेमी² के लिए गत्ते का व्यय = ₹ 4 /1000

2184 × 250 सेमी² के लिए गत्ते का व्यय = (4 /1000) × (2184 × 250)  = ₹ 2184  

अतः, प्रत्येक प्रकार के 20 डिब्बे बनवाने के लिए ₹ 2184 की लागत आएगी।

आशा है कि यह उत्तर आपकी मदद करेगा।

Answer»

Answer:

R1 : r2 =∛9/4

Step-by-step EXPLANATION:

given , VOLUME of SPHERE = volume of cylinder

          4/3π(r1)³ = π(r2)²h and h = 3(r2)

         put the value of h .

         4/3π(r1)³ = π(r2)²{3(r2)}

         4/3π(r1)³ = 3π(r2)³

The interior angle of a polygon are in A.P.The smallest angle is 94º and the commondifference is 7º. Find the number of sides ofthe polygon.​

Answer»

Answer:

Number of sides=5

Step-by-step explanation:

Let no of sides=X

then SUM of ANGLES=(2x-4)90

Now in AP

a=94 d=7,n=x

then sum of the AP

=x/2(2*94 + (x-1)*7)=(2x-4)90

x(188+7x-7)=180(2x-4)

x(7x+181)=360x-720

7x²+181x-360x+720=0

7x²+181x-360x+720=0

7x²-179x+720=0

x=( 179 ±√(32041-4*7*720)/14

=( 179 ±√32041-20160/14

=(179±√11881)/14

=(179±109)/14

x=179-109/14

or x=70/14=5

Hence x=5

Number of sides=5

==========================

for other value of x=179+109/14=288/14=20.57

this is not perfect no. so can not be no. of sides
