1.D)TRICKS – Option Choice

Or

According to question

(3X-25)/(X-25) = 19/3

X= 40 litre

∴The initial quantity of milk inn jar A = 3 * 40= 120 litre

2.A)TRICKS

24 * 3*X= 27 * 2*1/6

X= 1/8

∴Remaining work = 1-(1/8)= 7/8

3.D)TRICKS – option choice

Or

According to question

6X+5Y= 3880

3X + 2Y= 1750

Solving equation I & II

X= 330 , Y= 380

∴Price of 3 trousers =Rs 380 * 3= Rs 1140

4.C)TRICKS

RATIO METHOD

A:B=120 :100 = 6:5

C:A= 140 :100= 7:5

A:B:C= 30:25:42

Difference of B & C= 17

So 17 ⟹1122

30 ⟹ (1122 *30)/17= 1980

OR

Let the population of village B= X

Population of village A= X * (120/100)

Population of village C= 120/100 * 140/100

According to question

120/X * 140/X – X = 1122

X= 1650

Hence Population of village A = 1650 * ( 120/100) = 1980

5.B)

Sixth number = 10 * 21.8 – ( 4 *15 + 5*23) =43

6.D)TRICKS

Let the initial marked price of the luxury pen = Rs X

4536= X * 70/100 * 120/100

X= 5400

7.A)TRICKS

Let the present age of A =X years

The present age of B = (2X +4) years

According to question,

(X +6)/(2X +4+2) = 4/7

Hence X= 18 years

Present age of B = 2*18 + 4= 40 years

∴present age of C = 40 + 2 = 42 years

8.D)TRICKS

Let A invested in the business = X months

B invested in the business = (X-4)months

According to the question

25X/15(X-4)= 5/2

X=12

So (X-4)=8 months

9.D)TRICKS

Check option

10.C)TRICKS

Let the distance between A & B = D km

According to question

D/5-D/6= 15

S= 450 km

11.B)TRICKS

Let Sam invested in scheme A= Rs X

Sam invested in scheme B = Rs 2X

According to question

12960 * 100= 2X(100 + 24)- X ( 100 + 40)

X= 12000
