B किसी काम को जितने समय में करता है उसके 1/6 समय में A आधाकाम करता है, यदि काम को पूरा करने के लिए दोनों को कुल 10 दिनलगते हैं, तो B अकेला उस काम को कितने समय में करेगा?s.s.C. स्नातक स्तरीय परीक्षा, 2001, 02​

Answer»

Step-by-step explanation:

Given A does half as much work as B in 1/6 TH of the time. If they take 10 days to complete the work together, how much time shall B ALONE take to do it?

LET the time taken by B alone to complete the work be m days.

Now time taken by A to complete half of the work will be m / 6 days.

So work done by A for one day = 1/2 x 6 / m = 3 / m

Therefore work done by B for one day will be 1/m

So total will be 3/m + 1/m = 1/10

                            4 / m = 1/10

                         Or m = 40 days.

So B alone will do the work in 40 days

Split 60 in two parts such that three-sevenths of one part should be equal to the three-fifths of otherpart. Find the parts.​

Answer»

ANSWER:

FIRST part = 35

second part = 25

Step-by-step explanation:

Let the first part be X .

The second part is 60 - x .

3/7x = 3/5 (60 - x)

= 3/7 x = 36 - 3/5x

=3/5 x + 3/7 x = 36

= 36 / 35 x = 36

So , x = 35

First part = 35

second part = 25

(You can verify by SUBSTITUTING the values of x )

1. Form a quadratie polynomials Whose zeros are 2-√2/6 and 2+√2/6​

Answer»

Answer:

a = 2 - √2/6

b = 2 + √2/6

Q= x²- (a + b) x + a(b)

Q = x² - (2-√2/6 + 2+√2/6)x +2-√2/6(2+√2/6)

Q = x²- ( 2-√2 + 2+√2/6)x + 4 - 2 /6

Q = x² - (4/6 ) x + 2/6

Q = x²- 2/3 x + 1/3

If x+1/x=11, find the value of x^2+1/x^2​

Answer»

Step-by-step explanation:

Given -

  • x + 1/x = 11

To FIND -

  • Value of x² + 1/x²

Now,

→ x + 1/x = 11

Squaring both sides :-

→ (x + 1/x)² = (11)²

→ x² + 1/x² + 2×x×1/x = 121

→ x² + 1/x² + 2 = 121

→ x² + 1/x² = 121 - 2

→ x² + 1/x² = 119

Hence,

The value of + 1/x² is 119
