Question
In a warehouse, there are 200 washing machines and 300
microwaves. The average price of a washing machine is Rs. 15,000 while the average price of a microwave is Rs. 10,000. Find the average price (in Rs.) of all the washing machines and microwaves.Solution
ATQ,
Required average = (200 × 15000 + 300 × 10000) ÷ (200 + 300)
= (3000000 + 3000000) ÷ 500
= (6000000 ÷ 500) = Rs. 12,000

12.5% of (100 + ?) = 40
2/9 of 5/8 of 3/25 of ? = 40
24 × √? + 4008 ÷ 24 = 40% of 200 + 327
7(1/2) – 3(5/6) = ? − 2(7/12)
280 ÷ 14 + 11 × 12 – 15 × 6 = ?
1550 ÷ 62 + 54.6 x 36 = (? x 10) + (28.5 x 40)
25% of 1000 + 10% of 150 – 22 × ? = 45
√ 729 × 5 – 220 % of 15 + ? = 120% of 160
What will come in the place of question mark (?) in the given expression?
(40% of ? × 43 ) – 232 = 751
180 % of 45 + √144 × 8 = ?2 + 80 % of 70
