If 40% of 70 is x more than 30% of 80, then find x.

${\huge{\red{\underline{\underline{Answer}}}}}$

${\pink{\underline{\underline{Given}}}}$

40%of 70=x+30%of 80

${\pink{\underline{\underline{To\ find}}}}$

Value of x =???

${\pink{\underline{\underline{Solution}}}}$

According to given conditions;

40%of 70=x+30%of 80

=>$\frac{40}{100}×70=x+\frac{30}{100}×80$

=>$\frac{2800}{100}=x+\frac{2400}{100}$

=>28=x+24

=>x=28-24

=>x=4

Hence,the value of x is 4
