H^2=2pb
h^2=p^2 + b^2
p^2+ b^2=2pb
p^2 + b^2 -2pb=0
(p-b)^2=0
p-b=0
p=b
since both sides are equal
angle=45

Let 7 pencils & 4 erasers cost Rs y. and each pen costs Rs x.
=>cost of 14 pencils and 8 erasers=2y.
=>Amal paid: 5x+y & the other one paid 6x+2y
Now, (5x+y)/(6x+2y)=2/3(i.e, ration of sums paid by both of them)

=>y=3x;
so the %ge of pen price=(5x/8x)*100=62.5

The math

20% of 100 is 20 = 80% milk | 20% water
20% of 80 is 16, 16 + 20 is 36, 100 minus 36 = 64% milk | 36% water
20% of 64 is 12.8, 12.8 + 36 is 48.8, 100 minus 48.8 = 51.2% milk | 48.8% milk

A. 22 years
B. 18 years
C. 15 years
D. 20 years

suman

• May 18th, 2016

Let, at present sons age = x
so, fathers age = 3x

and after 2.5 years sons age will be = (x+2.5) yrs
so,fathers age will be = (3x+2.5) yrs

so, according to the problem,

3x+2.5=2.5(x+2.5)
or, x=3.75/0.5
or, x=7.5
so, now fathers age will be 22.5 yrs
