a, b, c ... in AP.

∴ 2b = a + c .......... (1)

∴ To Prove : 1/(√b + √c), 1/(√c + √a), 1/(√a + √b) ... in AP

⇒ To Prove : [ 1/(√c+√a) ] - [ 1/(√b+√c) ] = [ 1/(√a+√b) ] - [ 1/(√c+√a) ]

⇒ To Prove : [ (√b-√a) / (√b+√c) ] = [ (√c-√b) / (√a+√b) ]

⇒ To Prove : (√b-√a)·(√b+√a) = (√c-√b)·(√c+√b)

⇒ To Prove : b - a = c - b

⇒ To Prove : 2b = a + c, which is True ... from (1)

For 1st year , Amount=₹50,000=P, Time=T=1 year and Rate=12% .

Simple Interest obtained=P*R*T/100 =50000*12*1/100 =₹6000.

Amount after one year =₹50000+ ₹6000=₹56000.

Amount paid by jaya at end of first year= ₹56000-₹33000=₹23000.

Rate=15% p.a.=R and time =T=1year .

Amount to be paid at end of second year

=₹23000 +₹23000*15*1/100 =₹23000+₹3450=₹26450.

x=(1,6);y=(2,5) this is the value

x=(1,6);y=(2,5) this is the value .

x + y = 7(i) When x = 1 x + y = 7 1 + y = 7 y = 7 - 1 y = 6 (x,y) = (1,6)(ii) When y = 5 x + y = 7 x + 5 = 7 x = 7 - 5 x = 2 (x,y) = (2,5)

x+y=71) When x=1, x+y=7 1+ y = 7 y = 7-1 y = 6 (x,y) = 1,62) When y=5, x+y=7 x+5=7 x=7-5 x=2 (x,y) = 2,5

Let the two numbers be x and y,given that 60% of x = 40% of y

let us form equations,0.6 *x = 0.4*y ---- (1)=> y = (6/4)*x = 1.5 *x

it is also given that the sum of the numbers is 320.

x + y = 320=> x + 1.5*x = 320=> 2.5 *x = 320=> x = (320/2.5)=> x = 128

the larger number will be yy = 320 - 128= 320 - 128=192

Given that

Perimeter of a rectangular sheet = 100cm

Length = 35cm

Solution

Let the breadth of a rectangular sheet be x cm.Then,

according to question,

Perimeter of a rectangular sheet = 2(l+b)

=> 100 = 2(35+b)

=> 100/2 = 35+b

=> 50 = 35+b

=> -b = 35-50

=> -b = -15

=> b = 15cm

Area of a rectangular sheet = l×b

= (35×15)cm^2

= 525cm^2

perimeter=100=100÷2=50=50-35=15

Answer: 15 is the breadth

she is 39th person from the back

Her, position from the end=53-15+1=39th position.

1) Let the cost price of the purse be ₹x. Then,Loss = 1/6 of ₹x= ₹x/6Cost Price = Selling Price + Lossx = 250 + x/6x - x/6 = 2506x - x/6 = 2505x/6 = 250x = 250×6/5x = 300Hence, the cost price of the purse is ₹300.

2) Loss = Cost Price - Selling Price= ₹(300-250)= ₹50Loss % = Loss/Cost Price × 100= 50/300 × 100= 50/3 %= 16 unit 2/3 %.
