Answer: Option C

Explanation:

Let, Smaller number be x and larger be x

and larger number y

ATQ, 4x = 3y - 5

= > 4x - 3y = - 5 .............(i)

And, x + y = 6 (y - x) + 6

= > x + y - 6y + 6x = 6

= > 7x - 5y = 6 ..........(ii)

(i) × 5 - (ii) × 3

= x = - 43

∴x = 43

From (i) 4 × 43 - 3y = - 5

= > - 3y = - 5 - 172 = - 177

∴y = (177/3)

= 59

∴(y,x) = (59,43) (Ans) .

Answer: Option D

Explanation:

Given that,

the ratio of the business of P and Q is = 2 : 3

Let ,

P's investment is = 2x

Q's investment is = 3x

Again,

P's investment year is = 1 yr

Q's investment year is = 2 yr

Then,

P and Q investment is = 2x : 3X2x

= 2x : 6x

= 1 : 3

Q's profit is = 26000 x ¾

= 6500x 3

= 19500

So the above answer is none of them.
