16.	a and b work together complete a task in 30 days.a having work for 16 days b finushes the remaining work alone in 44 days.in hoe many days b alone can finish a work
Answer» Let A finishes the work in x days in 1 DAY, work completed by A = 1/x In 16 days , work = 16/x work let B finishes the work in y days In 44 days work done by B = 44/y work so, 16/x + 44/y = 1 .........( i ) & 1/x + 1/y = 1/ 30 .......( ii ) eq. ( i ) - ( ii ) x 16 16/x + 44/y - 16/x - 16/y = 1 - 16/30 28/y = 14/30 y = 60 Time TAKEN by B alone = 60 days

16.

a and b work together complete a task in 30 days.a having work for 16 days b finushes the remaining work alone in 44 days.in hoe many days b alone can finish a work

Answer»

Let A finishes the work in x days

in 1 DAY, work completed by A = 1/x

In 16 days , work = 16/x work

let B finishes the work in y days

In 44 days work done by B = 44/y work

so,

16/x + 44/y = 1 .........( i )

& 1/x + 1/y = 1/ 30 .......( ii )

eq. ( i ) - ( ii ) x 16

16/x + 44/y - 16/x - 16/y = 1 - 16/30

28/y = 14/30

y = 60

Time TAKEN by B alone = 60 days

34.

What is the percentage increase in the area of a triangle if it's each side is doubked

Answer»

Let a,b,c be the sides of the original ∆ & s be its semi perimeter.

S= (a+b+c)/2

2s= a+b+c.................(1)

The sides of a new ∆ are 2a,2b,2c

[ given: Side is DOUBLED]

Let s' be the new semi perimeter.

s'= (2a+2b+2c)/2

s'= 2(a+b+c) /2

s'= a+b+c

S'= 2s. ( From eq 1)......(2)

Let ∆= AREA of original triangle

∆= √s(s-a)(s-b)(s-c).........(3)

&

∆'= area of new Triangle

∆' = √s'(s'-2a)(s'-2b)(s'-2c)

∆'= √ 2s(2s-2a)(2s-2b)(2s-2c)

[From eq. 2]

∆'= √ 2s×2(s-a)×2(s-b)×2(s-c)

= √16s(s-a)(s-b)(s-c)

∆'= 4 √s(s-a)(s-b)(s-c)

∆'= 4∆. (From eq (3))

Increase in the area of the triangle= ∆'- ∆= 4∆ - 1∆= 3∆

%increase in area= (increase in the area of the triangle/ original area of the triangle)× 100

% increase in area= (3∆/∆)×100

% increase in area= 3×100=300 %

Hence, the percentage increase in the area of a triangle is 300%
