Direction (1-5) :

90 + (280/4) – 151 = ∛x

90 + 70 – 151 = ∛x

9 = ∛x

X = 93 = 729

182 ÷ 32 × 90 ÷ 5 = x – (552/4)

[(18*18)/(3*3)]*(90/5) = x – (552/4)

648 + 138 = x

X = 786 = 790

(5/7) of 343 + (2/3) of (7/15) of 1890 = x % of 700

(5/7) * 343 + (2/3) * (7/15) * 1890 = (x/100)*700

245 + 588 = 7x

833 = 7x

X = 833/7

X = 119

√x + 28 = (375 + 72) ÷ 50 + (19 × 3)

√x + 28 = 447/50 + 57

√x = 9 + 57 – 28

√x = 38

X = 382 = 1444

36 % of 490 + 52 % of 300 = 4 × ?

(36/100)*490 + (52/100)*300 = 4x

4x = 176.4 + 156

4x = 332.4

X = (332.4/4) = 83.1

X = 83

Direction (6-10) :

The total export of Cotton in the period of March to August

= > [27 + 32 + 36 + 26 + 38 + 24]*(29/100)

= > 183*(29/100)

= > 53.07 billion dollars

Required average = 53.07/6 = 8.845 billion dollars

Total export of Plastics and Chemical products in the month of May and June together

= > 36*(30/100) + 26*(30/100)

= > 10.8 + 7.8

= > 18.6 billion dollars

Total export of Iron and steel and Meat in the month of July and August together

= > 38*(41/100) + 24*(41/100)

= > 15.58 + 9.84

= > 25.42 billion dollars

Required % = (18.6/25.42)*100 = 73.17 % = 73 %

The total exports of Meat in the month of March, May and July together

= > (27 + 36 + 38)*(17/100)

= > 17.17 billion dollars

The total exports of Iron and Steel in the month of April, June and August together

= > (32 + 26 + 24)*(24/100)

= > 19.68 billion dollars

Required difference = 19.68 – 17.17 = 2.51 billion dollars

The total exports of Cotton in the month of June and August together

= > (38 + 24)*(29/100)

= > 17.98 billion dollars

The total exports of Chemical products in the month of March and April together

= > (27 + 32)*(18/100)

= > 10.62 billion dollars

Required ratio = 17.98 : 10.62 = 899 : 531

Total exports of Cotton and Meat in the month of March and August together

= > (27 + 24)*[(29 + 17)/100]

= > 23.46 billion dollars

Total exports of Iron and Steel and Chemical products in the month of April and June together

= > (32 + 26)*[(24 + 18)/100]

= > 24.36 billion dollars

Required %

= > [(24.36 – 23.46)/24.36]*100 = 3.69 %

= > 4 % less
