x is 20% more than z and y is 80% more than z. Find x:y ?
A. 2:3
B. 1:3
C. 1:4
D. 3:4x = z+(20/100)z = 1.2z y = 1.8z x:y = 1.2z:1.8z = 12:18 = 2:3
A, B, C and D divide a sum of money among themselves in the ratio 7:4:3:2. If D gets Rs. 500 less than A, find the total amount ?
A. Rs.340
B. Rs.780
C. Rs.100
D. Rs.1600Two kinds of rice, 1st costs Rs.13 per kg and 2nd costs Rs.19 per kg are mixed together. Find the ratio in which the 2 types are mixed so that the mixture costs Rs.14.2 per kg ?
A. 3:4
B. 4:3
C. 4:1
D. 3:1Therefore, 13x + 19(1-x) = 14.2
13x -19x + 19 = 14.2
4.8 = 6x
x = 0.8 ; (1-x) = 0.2
Therefore, the ratio is 0.8 : 0.2 = 4:1X, Y and Z are quantities of the same kind such that X:Y=5:8 and Y:Z=4:7. Find X:Z ?
A. 5:14
B. 5:7
C. 32:35
D. 67:56X:Z=(X:Y)*(Y:Z) =(5:8)*(4:7) = (5/8)*(4/7) = 5/14
Third proportional to 3.5, 5.6 is ____ ?
A. 15.7
B. 19
C. 7
D. 8.963.5/5/6 = 5.6/x ; x = 5.6 * 5.6 / 3.5 = 8.96
Ratio of two numbers is 5:9. If each number is decreased by 5, the ratio becomes 5:11. Find the numbers ?
A. 15, 34
B. 15, 27
C. 30, 19
D. 21, 37(5x-5)/(9x-5) = 5:11
(5x-5)*11 = (9x-5)*5
55x – 55 = 45x – 25
10x = 30
x = 3
Therefore, the numbers are 15 and 27.Divide Rs.2000 into two shares in the ratio 3:2 ?
A. Rs.1500,Rs.500
B. Rs.1100, Rs.900
C. Rs.1200,Rs.800
D. Rs.800,Rs.12003x+2x=2000 5x=2000 x=400 3x=1200 2x=800
A bag contains 1 rupee, 2 rupee and 5 rupee coins amounting to Rs.264. If the ratio of the number of these coins is 3:5:4, find the number of 1 rupee coins ?
A. 13
B. 76
C. 41
D. 24Let the number of 1 rupee, 2 rupee and 5 rupee coins be 3x, 5x and 4x. (1*3x)+(2*5x)+(5*4x)=264 3x+10x+20x=264 33x=264 x=8 No. of 1 rupee coins
= 3x = 24If x% of 200=y% of 250, find y:x ?
A. 4:5
B. 2:5
C. 5:4
D. 5:2(x/100)*200 = (y/100)*250 y/x = 20/25 = 4/5 y:x=4:5
In a partnership for a business, Changaz invests Rs.6000 for complete year & Nasir invests Rs.3000 for 6 months. What is Nasir’s share if they earn Rs.240 as profit ?
A. 12
B. 48
C. 120
D. 192for T2 time and his share of profit is P2, then, C1 * T1 / C2 * T2 = P1/P2
If P is the Nasir’s share of profit, then Changaz gets (240 – P)
Therefore, 6000 * 12 / 3000 * 6 = (240 – P) / P = 72/ 18 = 4
4P = (240 – P)
5P = 240
P = 48
