Question

1. After spending 69 p.c. of her money, a lady has 93 left. How much had she at first ?
2. 17% of a certain number of mangoes go rotten; find the number of mangoes if 1360 go rotten​

Answer 1

Answer:

1. Rs.300 and 2. 8000

Step-by-step explanation:

1. Let x be the amount she had

x-69%x=93

x-69x/100=93

100-69x/100=93

31x/100=93

x=93×100/31

x=Rs.300

69% of 300=207

=300-207

=93

prooved

She had Rs.300

2. let total number of mangoes be " x "  

according to question ,

17 % = 1360

100% = x

by cross multiplication , we get

17x = 1360 × 100

17x = 136000

x = 136000 / 17

x = 8000

HENCE Number of mangoes is 8000

Answer 2

1. 300
2. 8000

If the lady spent 69% of her money then she will have 31% so if 31% of her money is ₹93 then the 69% of her money will be 300 simply cross multiply

In 2. The 17% of mango get rotten and the 17%= 1360 then the 100% will be 8000 we can find it with cross multiply
