Solution

2*(1/128)*[{(10, 00, 000*16/100) 1/4} 3] 2 = 10, 00, 000

Correct Option: 6 Best Solution (9)

Dr.Dipin Singh   14 years AGO

16 % of 10 lacs = 160000 = (20)^4......fourth root of 16 % of 10 lacs= 20........cube of fourth root of 16 % of 10 lacs = 20^3= 8000.............
square of cube of fourth root of 16 % of 10 lacs = 8000^2..........one twenty eighth part of square of cube of fourth root of 16 % of 10 lacs = (8000^2)/128............Double of one twenty eighth part of square of cube of fourth root of 16 % of 10 lacs = 2*(8000^2)/128= [2*8^2*(10)^6]/128 = 10^6 = 1000000... option 6

>> 10,00,000*(0.16) >> 1,60,000
>> fourth root(1,60,000) >> 20
>> 20^3 >> 8000
>> (8000)^2 >> 6,40,00,000
>> (6,40,00,000)*(1/128) >> 5,00,000
>> 2(5,00,000) >> 10,00,000

shailender   14 years AGO

10,00,000*(0.16)=1,60,000
1,60,000 fourth root is =20
20"s cube is 8,000
square of this is 64,000,000
128 th part is 64,000,000/128
double of this is 10,00,000

4 th root of{16/100(1000000)}=20
then {(20)^6/128}*2= 1000000

Abhishek Mukherjee   14 years AGO

16%of 1000000=160000
4th root of 160000=20
cube of 20=8000
sq of 8000=64000000
128th part=500000
500000*2=1000000
