2) 40.09% of 80.15 + 60.04% of 160.12 = ?

Explanation

It can be written as 40% of 80 + 60% of 160
40% of 80 = 32
60% of 160 = 96

32+96 = 128

3) 40% of 265 + 35% of 180 = 50% of ? + ?% of 80

Explanation

Let the missing value be y
40% of 265 = 106
35% of 180 = 63
106 + 63 = 169 = 50% of y + y% of 80

169 = y/2 + 4y/5
y = 130

Submit
4) √? + 416 = (60% of 920) - 110

Explanation

√? + 416 = (60% of 920) - 110
√? + 416 = ( 6 × 92) − 110
√? + 416 = 442
√? = 26
? = 676

Submit
5) 1/4 * 117  - 1/3 * 15 + ? = 40

Explanation

This can be written as 1/4 * 116 + 1/3 * 15 + ? = 40

29 + 5 + ? = 40
? = 16 (approx)

So the closest option 17 is the answer

Submit
6) (682% of 782)  / 856 = ?

Explanation

682/100 * 782 / 856 = 6.2

Submit
7) 15.5% of 850 + 24.8% of 650 = ? 

Explanation

15.5% of 850 = 15% of 850 = 10% + 5% = 131.75 (approx)
24.8% of 650 = 25% of 650 = 1/4 th of 650 = 162.5 (approx)
So total we get approximately 293

Submit
