6. In an ice-cream factory, 30% of total Vanilla-flavored ice-cream produced is mixed with 40% of total Banana-flavored ice-cream produced, in a ratio of 1:1. Find the overall percentage of ice-cream produced (approximately) which is mixed with each other. (Ice-creams of only these 2 flavors are produced in the factory)
1)29%
2)35%
3)21%
4)42%
5)34%

Answer & Solutions

Option: 5

Explanation: Let the total Vanilla-flavored ice-cream produced and total Banana-flavored ice-cream produced be x and y respectively
Given,30% of x = 40% of y (Since ratio is 1:1)………….(1)
=> x/y=4/3
=> x/y+1=4/3+1(On adding 1 to both sides of the equation)
=> (x+y)/y=7/3
=> y/(x+y)=3/7
Total ice-cream mixed = 0.3x + 0.4y = 0.4y + 0.4y = 0.8y (from (1))
% of overall ice-cream mixed = 0.8y/(x+y)×100=0.8×3/7×100 = 34.28%~34%

 

7. Two persons A and B start moving at each other from point P and Q respectively which are 1400 Km apart. Speed of A is 50 Km/hr and that of B is 20 Km/hr. How far is A from Q when he meets B for the 22nd time?
1)11100km
2)900km
3)400km
4)1200km
5)700km

Answer & Solutions

Option: 3

Explanation: Total distance travelled by both of them for 22nd meeting = 1400 + 21 x 2 x 1400 = 43 x 1400
Distance travelled by each will be in proportion of their speed:-
Therefore, distance travelled by A = 50/(50 + 20) x 43 x 1400 = 43000
Now, for every odd multiple of 1400, A will be at Q and for every even multiple of 1400 A will be at P. So, at 42000 Km (1400 x 30, even multiple) A will beat P. So at their 22 meeting, A will be 1000 Km from P, therefore, 400 Km from Q.

 

8. In an examination the candidate was asked to attempt 50 questions where all the questions were mandatory.1 mark is given for each correct answer and 25% of the correct answer’s mark is deducted if answer is incorrect.

1)36
2)09
3)27
4)18
5)24

Answer & Solutions

Option: 4

x-(50-x)/4=27.5
=>x=32..So no of incorrect answers=(50-32)=18
