Defective laptops in Samsung = 30/100 * 14000 = 4200

Non defective laptops in Lenovo = 75/100 * 12000 = 9000

Required percentage = 4200/9000 * 100 = 46.67%

Non defective laptops = 90/100 * 18000 = 16200

Sold non defective laptops = 16200 * 80/100 = 12960

Revenue collection = 12960 * 40000 = Rs.518400000

Non defective laptops of Dell = 80/100 * 16000 = 12800

Defective laptops of Apple = 5/100 * 20000 = 1000

Required ratio = 12800: 1000

= 64: 5

Defective laptops of Dell = 20/100 * 16000 = 3200

Defective laptops of Sony = 10/100 * 18000 = 1800

Defective laptops of Samsung = 30/100 * 14000 = 4200

Defective laptops of Apple = 5/100 * 20000 = 1000

Defective laptops of Lenovo = 25/100 * 12000 = 3000

Average = (3200 + 1800 + 4200 + 1000 + 3000)/5 = 2640

Required percentage = 12000/18000 * 100 = 66.67%

53 xÂ 54Â Ã· 52Â = 5(13 – ?)

7 â€“ 2 = 13 – ?

? = 8

(56 x 0.25)4Â Ã· (6860 Ã· 35)4Â x (343 x 8)4Â = (7 x 2)(?) +11

(7 x 2)4Â Ã· {(7 x 2)2}4Â x {(7 x 2)3}4Â = (7 x 2)(x+11)

4 â€“ 8 + 12 = x + 11

x = -11 + 8 = -3

? = 6(1 + 11 + 111 + 1111 + 11111) â€“ (22 + (2320 â€“ 16)1/2)

? = 6(12345) â€“ (22 + 48)

? = 74070 – 70 = 74000

[{66 – 11} % of 660] % of 25 = x % of 165

[55 % of 660] % of 25 = x % of 165

363 % of 25 = x % of 165

? = 9075/165 = 55
