@Efflorescences sir btana ise

a+b+c+d=10.....13C3
b+c+d=10......12C2

13C3 - 12C2 - 1 = 219

@Efflorescences sir इसे सॉल्व कर देना 😐

@Efflorescences sir 😐

Sir ese nehi Hoo sakta ?

Let side =x,y,z
Z²=x²+y²---3y²=3z²-3x²----@@(1)
Median ke leangth a,b,c
A²+b²=c²
A²=x²+y²/4
B²=z²/4
Add
Y²+x²/4=x²+y²/4+z²/4
3/4y²=3/4x²+z²/4
3y²=3x²+z²
Equate form 1
3z²-3x²=3x²+z²
6x²=2z²
X/z=1/√3
Put it in any
Y=√2
Ratio =1:√2:√3

Baaki option se bhi ho jayega

Please 🙏

X. Y
30. 45
90
3. 2
3*8+2*7=38
90*.7=63
25 in 15 hours
5. In. 3
10 in 6
15. In 6
*6. *6
90. In 36

x y z

30 45

lcm( 90)

opennig provedure
xz, yz, xz yz...........xz

90x70/100= 63 unit
x worked 8 hours = 24 unit
y works 7 hours= 14 unit
z works 15 hour= 63-38=25


15 hour me 25 unit
3 hour me 5
6 hour me 10 unit
increased by 50%
6 hours = 15 unit

total time taken by z = 6x6= 36 hours.✅✅✅
