Answer» ᴴeʸ ᵐaᵗe ʰeʳe iˢ ʸouʳ aⁿˢʷeʳ⁻ We can SEE in the FIGURE attached that - He goes 24m west and 7m north. So to find the DISTANCE between the starting and ending point, we will apply pythagoras theoram. So LET the distance be x So, x^2= (24)^2+7^2 x^2=576+49 x^2=625 x=√625 x=25 m So the answer is 25m.

6.

A man goes 24 m due West and then7 m due North. Then, he is ......... m awayfrom the starting point.

Answer»

ᴴeʸ ᵐaᵗe ʰeʳe iˢ ʸouʳ aⁿˢʷeʳ⁻

We can SEE in the FIGURE attached that -

He goes 24m west and 7m north.

So to find the DISTANCE between the starting and ending point, we will apply pythagoras theoram.

So LET the distance be x

So,

x^2= (24)^2+7^2

x^2=576+49

x^2=625

x=√625

x=25 m

So the answer is 25m.

16.

Raju is 19 years younger than his cousin after 5 years their age will be in ratio 2: 3 find their present age

Answer»

Step-by-step explanation:

Lets take Raju's cousin's AGE be x yrs

Lets take Raju's cousin's age be x yrsTherefore Raju 's age = x - 19

Lets take Raju's cousin's age be x yrsTherefore Raju 's age = x - 19Ratio between Raju and his cousin = 2 : 3 or 2/3

Lets take Raju's cousin's age be x yrsTherefore Raju 's age = x - 19Ratio between Raju and his cousin = 2 : 3 or 2/3Hence (x - 19) + 5/x + 5 = 2/3

Lets take Raju's cousin's age be x yrsTherefore Raju 's age = x - 19Ratio between Raju and his cousin = 2 : 3 or 2/3Hence (x - 19) + 5/x + 5 = 2/3= 5 + x - 5 + 19/x + 5 = 2/3

Lets take Raju's cousin's age be x yrsTherefore Raju 's age = x - 19Ratio between Raju and his cousin = 2 : 3 or 2/3Hence (x - 19) + 5/x + 5 = 2/3= 5 + x - 5 + 19/x + 5 = 2/3= 5 + x - 14/x + 5 = 2/3

Lets take Raju's cousin's age be x yrsTherefore Raju 's age = x - 19Ratio between Raju and his cousin = 2 : 3 or 2/3Hence (x - 19) + 5/x + 5 = 2/3= 5 + x - 5 + 19/x + 5 = 2/3= 5 + x - 14/x + 5 = 2/3= 15 + 3x - 42/2x + 10

Lets take Raju's cousin's age be x yrsTherefore Raju 's age = x - 19Ratio between Raju and his cousin = 2 : 3 or 2/3Hence (x - 19) + 5/x + 5 = 2/3= 5 + x - 5 + 19/x + 5 = 2/3= 5 + x - 14/x + 5 = 2/3= 15 + 3x - 42/2x + 10= - 37 + 3x = 2x+10

Lets take Raju's cousin's age be x yrsTherefore Raju 's age = x - 19Ratio between Raju and his cousin = 2 : 3 or 2/3Hence (x - 19) + 5/x + 5 = 2/3= 5 + x - 5 + 19/x + 5 = 2/3= 5 + x - 14/x + 5 = 2/3= 15 + 3x - 42/2x + 10= - 37 + 3x = 2x+10= - 37 - 10 = 2x - 3x

Lets take Raju's cousin's age be x yrsTherefore Raju 's age = x - 19Ratio between Raju and his cousin = 2 : 3 or 2/3Hence (x - 19) + 5/x + 5 = 2/3= 5 + x - 5 + 19/x + 5 = 2/3= 5 + x - 14/x + 5 = 2/3= 15 + 3x - 42/2x + 10= - 37 + 3x = 2x+10= - 37 - 10 = 2x - 3x= - 47 = - x

Lets take Raju's cousin's age be x yrsTherefore Raju 's age = x - 19Ratio between Raju and his cousin = 2 : 3 or 2/3Hence (x - 19) + 5/x + 5 = 2/3= 5 + x - 5 + 19/x + 5 = 2/3= 5 + x - 14/x + 5 = 2/3= 15 + 3x - 42/2x + 10= - 37 + 3x = 2x+10= - 37 - 10 = 2x - 3x= - 47 = - x= 47 = x = His cousin age after 5 yrs=47 + 5 = 52yrs

Lets take Raju's cousin's age be x yrsTherefore Raju 's age = x - 19Ratio between Raju and his cousin = 2 : 3 or 2/3Hence (x - 19) + 5/x + 5 = 2/3= 5 + x - 5 + 19/x + 5 = 2/3= 5 + x - 14/x + 5 = 2/3= 15 + 3x - 42/2x + 10= - 37 + 3x = 2x+10= - 37 - 10 = 2x - 3x= - 47 = - x= 47 = x = His cousin age after 5 yrs=47 + 5 = 52yrs= His age = 52 - 19 = 33yrs

36.	sum of the digits of a two digit number is 12 new number formed by reversing the digit is greater than the original number by 54 find the original number
Answer» Step-by-step explanation: => Let the digit in ones place be x => So, the digit in tens place be 12 - x => Original no. = 10(12 - x) + 1(x) => 120 - 10x + x => 120 - 9X => New no. = 10(x) + 1(12 - x) => 10x + 12 - x = >9x + 12 [∵By reversing the DIGITS] According to QUESTION :- => New no. - Original no. = 54 =>(9x + 12) - (120 - 9x) = 54 ⇒ 9x + 12 - 120 + 9x = 54 ⇒ 18x - 108 = 54 ⇒ 18x = 54 + 108 ⇒ 18x = 162 ⇒ x = 162 / 18 ⇒ x = 9 Required Numbers - Original no. = 120 - 9x = 120 - 9(9) = 120 - 81 = 39 New no. = 93 [∵By reversing the digits] ∴ the required number is EITHER 39 or 93 ∴ Sum of digits = 3 + 9 = 12 The new number is greater than Original number by 54 verification :- New number = 93 Original number = 39 ∴ 39 < 93 ∴ 93 - 39 = 54

36.

sum of the digits of a two digit number is 12 new number formed by reversing the digit is greater than the original number by 54 find the original number

Answer»

Step-by-step explanation:

=> Let the digit in ones place be x

=> So, the digit in tens place be 12 - x

=> Original no. = 10(12 - x) + 1(x)

=> 120 - 10x + x

=> 120 - 9X

=> New no. = 10(x) + 1(12 - x)

=> 10x + 12 - x

= >9x + 12 [∵By reversing the DIGITS]

According to QUESTION :-

=> New no. - Original no. = 54

=>(9x + 12) - (120 - 9x) = 54

⇒ 9x + 12 - 120 + 9x = 54

⇒ 18x - 108 = 54

⇒ 18x = 54 + 108

⇒ 18x = 162

⇒ x = 162 / 18

⇒ x = 9

Required Numbers -

Original no. = 120 - 9x = 120 - 9(9)

= 120 - 81 = 39

New no. = 93 [∵By reversing the digits]

∴ the required number is EITHER 39 or 93

∴ Sum of digits = 3 + 9 = 12

The new number is greater than Original number by 54

verification :-

New number = 93

Original number = 39

∴ 39 < 93

∴ 93 - 39 = 54
