6.	Shripati sold a land for Rs. 2,50,000 to Mr. Sadashiv through a broker. Broker received 2% brokerage from both. Find the total brokerage received by the broker.
Answer» BROKER received BROKERAGE from Shripati = 2% of 250000 = 2 × 250000/100 = 2 × 2500 = 5000 Rs. again Broker received brokerage from SADASHIV = 2% of 250000 = 2 × 250000/100 = 2 × 2500 = 5000 Rs. hence, total brokerage received by the broker = 5000 + 5000 = 10,000 Rs.

Glad to answer this !

Derivation of Heron's Formula

Area of triangle ABC

A=1 /2bh → equation (1)

From triangle ADB

x2+h2=c2

x2=c2–h2

x=c2−h2−−−−−−√

From triangle CDB

(b–x)2+h2=a2

(b–x)2=a2–h2

b2–2bx+x2=a2–h2

Substitute the values of x and x2

b2–2bc2−h2−−−−−−√+(c2–h2)=a2–h2

b2+c2–a2=2bc2−h2−−−−−−√

Square both sides

(b2+c2–a2)2=4B2(c2−h2)

(b2+c2–a2)24b2=c2−h2

h2=c2−(b2+c2–a2)24b2

h2=4b2c2−(b2+c2–a2)24b2

h2=(2BC)2−(b2+c2–a2)24b2

h2=[2bc+(b2+c2–a2)][2bc−(b2+c2–a2)]4b2

h2=[2bc+b2+c2–a2][2bc−b2−c2+a2]4b2

h2=[(b2+2bc+c2)–a2][a2−(b2−2bc+c2)]4b2

h2=[(b+c)2–a2]⋅[a2−(b−c)2]4b2

h2=[(b+c)+a][(b+c)−a]⋅[a+(b−c)][a−(b−c)]4b2

h2=(b+c+a)(b+c−a)(a+b−c)(a−b+c)4b2

h2=(a+b+c)(b+c−a)(a+c−b)(a+b−c)4b2

h2=(a+b+c)(a+b+c−2a)(a+b+c−2b)(a+b+c−2c)4b2

h2=P(P−2a)(P−2b)(P−2c)4b2 note: P = perimeter

h=P(P−2a)(P−2b)(P−2c)−−−−−−−−−−−−−−−−−−−−−−√2b

Substitute h to equation (1)

A=12bP(P−2a)(P−2b)(P−2c)−−−−−−−−−−−−−−−−−−−−−−√2b

A=14P(P−2a)(P−2b)(P−2c)−−−−−−−−−−−−−−−−−−−−−−√

A=116P(P−2a)(P−2b)(P−2c)−−−−−−−−−−−−−−−−−−−−−−−−√

A=P2(P−2a2)(P−2b2)(P−2c2)−−−−−−−−−−−−−−−−−−−−−−−−−−−−−√

A=P2(P2−a)(P2−b)(P2−c)−−−−−−−−−−−−−−−−−−−−−−−−−−√

h2=(b+c+a)(b+c−a)(a+b−c)(a−b+c)4b2

h2=(a+b+c)(b+c−a)(a+c−b)(a+b−c)4b2

h2=(a+b+c)(a+b+c−2a)(a+b+c−2b)(a+b+c−2c)4b2

h2=P(P−2a)(P−2b)(P−2c)4b2 note: P = perimeter

h=P(P−2a)(P−2b)(P−2c)−−−−−−−−−−−−−−−−−−−−−−√2b

Substitute h to equation (1)

A=12bP(P−2a)(P−2b)(P−2c)−−−−−−−−−−−−−−−−−−−−−−√2b

A=14P(P−2a)(P−2b)(P−2c)−−−−−−−−−−−−−−−−−−−−−−√

A=116P(P−2a)(P−2b)(P−2c)−−−−−−−−−−−−−−−−−−−−−−−−√

A=P2(P−2a2)(P−2b2)(P−2c2)−−−−−−−−−−−−−−−−−−−−−−−−−−−−−√

A=P2(P2−a)(P2−b)(P2−c)−−−−−−−−−−−−−−−−−−−−−−−−−−√

Hence proved

Recall that P/2 = s. Thus,

A = \sqrt{s(s - a)(s - b)(s - c)}

31.	Ab and ba are 2 two-digit numbers such that ab + ba = cac. what is a+b+c ? (assume c is not 0 )
Answer» So, ab + ba = cac This situation can be written numerically as, 10a + b + 10 b + a = 100c + 10a + c 11a + 11b = 10a + 101c a + 11b = 101c Now, a and b are digits, HENCE they are 1 digit numbers So, The value of c MUST be definetly 1 , Reason : Let US take a and b as 2 digit numbers, 10 + 110 = 120 Now, 120 = 101 c So, c can be only 1 because c= 2 will make a and b 2 digit numbers So, a + 11b = 101 So, The only combination which satisfies this is (2, 9) So, a= 2 , b= 9 ,c =1 So, a + b +c = 2 + 9 + 1 = 12 So, The NUMBER is 12

31.

Ab and ba are 2 two-digit numbers such that ab + ba = cac. what is a+b+c ? (assume c is not 0 )

Answer»

So,

ab + ba = cac

This situation can be written numerically as,

10a + b + 10 b + a = 100c + 10a + c

11a + 11b = 10a + 101c

a + 11b = 101c

Now, a and b are digits,

HENCE they are 1 digit numbers

So,

The value of c MUST be definetly 1 ,

Reason :

Let US take a and b as 2 digit numbers,

10 + 110 = 120

Now,

120 = 101 c

So,

c can be only 1 because c= 2 will make a and b 2 digit numbers

So,

a + 11b = 101

So,

The only combination which satisfies this is

(2, 9)

So,

a= 2 , b= 9 ,c =1

So,

a + b +c = 2 + 9 + 1 = 12

So,

The NUMBER is 12
