### SOLUTIONS:

Direction (1-5) :
820 ÷ 21 × 3 +? ≈ 240
Or, 39 × 3 +? ≈ 240
Or,? ≈ 240 – 117 = 123
? ≈ (24.02)2 – 299 ÷ 12 × 13.95
≈ 576 – 25 × 14 = 576 – 350 = 226 ≈ 225
(?)3 + √49 = 92 × 876 ÷ √1296
(?)3 + 7 = 92 × 576 ÷ 36
(?)3 + 7 = 92 × 576 ÷36
(?)3 = 1465
?= 11.3
? = (21.5 * 10)1/3 + (43 * 6)1/2
? = (215)(1/3) + (258)(1/2)
? = (63)(1/3) + (162)(1/2)
? = 6 + 16 = 22
40 * (440/100) + ?/100 * 655 = 228
4*44 + ? * 6.55 = 229
? = (229 – 176) / 7
? = 53/7 = 7.5 = 8
Directions (6-10):
The expenditure of company A in the year 2013 = Rs. 138 lakhs
The income of company A in the year 2013
= > 138*(114/100) = 157.32 lakhs
The income of company B in the year 2014 = 138*(100/75) = 184 lakhs
The expenditure of company B in the year 2014
= >184*(100/115) = 160 lakhs
Required sum = 157.32 + 160 = 317.32 lakhs
The income of company A in the year 2015 = The income of company B in the year 2017 = x
The expenditure of company A in the year 2015 = x*(100/114)
The expenditure of company B in the year 2017 = x*(100/109)
Required ratio = [x*(100/114)] : [x*(100/109)]
= >109 : 114
The income of company A in the year 2015 = 95 lakhs
The expenditure of company A in the year 2015
= >95* (100/114) = 83.33 lakhs
The expenditure of company B in the year 2016 = 110 lakhs
The income of company B in the year 2016
= > 110*(115/100) = 126.5 lakhs
Required % = [(126.5 – 88.33)/126.5]*100 = 30.17 % = 30 % less
