The sum of three consecutive multiples of 7 is 777.find these multiples

Answer»

Hii
Here is Your answer
_______________________________________________________

Ist CONSECUTIVE multiple of 7 = x
IInd consecutive multiple of 7 = x + 7
IIIrd consecutive multiple of 7 = x + 14

A.T.Q

=> x + x + 7 + x + 14 = 777
=> 3x + 21 = 777
=> 3x = 777 - 21
=> 3x = 756
=> x = 756/3
=> x = 252

Hence, Ist consecutive multiples of 7 = x
= 252

IInd consecutive multiple of 7 = x + 7
= 252 + 7
= 259

IIIrd consecutive multiple of 7 = x + 14
= 252 + 14
= 266

If cosectheta=t+1/4t(t not included in fraction), then prove that cosectheta + cottheta = 2t or 1/2t

Answer»

√{(sec β -1)/(secβ +1)}

= √{(1 - cosβ)/(1+cosβ)} (by dividing every term by secβ

= √{(1-cosβ)²/(1-cos²β)} ( by multiplying numerator & denominator by (1-cosβ)

= √{(1- cosβ)² / sin²β }

= (1-cosβ) / sinβ …………………. (1)

Similarly, √{(secβ +1)/(secβ -1)

= √{(1+cosβ) / (1-cosβ) } ( as done above)

= √{(1+cosβ)² / (1-cos²β) }

= √{(1+cosβ)² / sin² β }

= (1+cosβ ) / sinβ ……………. (2)

By adding (1) & (2)

LHS =

= { 1-cosβ + 1+cosβ } / sinβ

= 2/sinβ

= 2 cosec β

= RHS

[ Hence PROVED]

The polynomials ax^3-x^2+4 and 2x^3-5x+a when divided by (x-2) leaves the remainder p and q respectively, if p-2q=4 find the value ofa.

Answer»

If a NUMBER 'a' and a number 'b' are DIVISIBLE by a number 'n' then, a+b and a-b is also divisible by n

=> let the number be n which divides 62, 132 and 237 leaving a REMINDER r

=> the REQUIRED number then becomes H.C.F of 62-r, 132-r and 237-r

=> it could also be the H.C.F of 
(132-r)-(62-r) and (237-r)-(132-r)

i.e. 70 and 105

=> H.C.F of 70 and 105 = 35

the required number n is 35.

7 men can complete a piece of work in 12 days they started the work and after 5 days two men left in how many days will the work be completed by the same element

Answer»

Total units of work = 7 men * 12 days = 84 units of work

For 5 days, 7 men worked => 7*5 = 35 units of work COMPLETED

Remaining (84 - 35) = 49 units of work need to be completed by (7 - 2) = 5 men

So, No. of days REQUIRED for remaining work to complete = 49/5 = 9 (4/5) days = 9.8 days
