What % of 780 is 259.2 ?
a) 33.23 b) 32.23 c) 31.23 d) 30.23
Answer : a) 33.23

Solution :

Let X% of 780 is 259.2
Then, (X/100)x780 = 259.2
780X/100 = 2592/10
78X = 2592
X = 2592/78 = 33.23

Hence the answer is option a.


Question 2
Find the value of X in X% of 1864 + 60 = 618.2
a) 19.04 b) 39.44 c) 29.94 d) 23.02
Answer : c) 29.94

Solution :
Given expression is X% of 1864 + 60 = 618.2
1864 x X/100 + 60 = 618.2
1864 x X/100 = 558.2
X = 5582/10 x 100/1864
X = 29.94
Hence the answer is option c.


Question 3
90% of 3000 + 70% of 3400 = ? % of 6350
a) 80 b) 60 c) 124 d) none of these
Answer : a) 80
Solution :

Given equation is: 90% of 3000 + 70% of 3400 = ? % of 6350

We have to find the value of '?'

Let ? be X.
Then, 90% of 3000 + 70% of 3400 = X% of 6350
3000x90/100 + 3400x70/100 = 6350X/100
3000x90 + 3400x70 = 6350X
27000+23800 = 635X
50800/635 = X
X = 80
Hence the required answer is 80.

X x 130/100 = 40x845/100
130X = 40x845
X = 40x845/135 = 250.37
Hence the answer is option d.
