1.	A merchand bought two calculators which together cost him 4800.He sold one of them at a loss of 15% and other at a gain of 19% . If the selling price of both the calculator is equal find the cost price of the lower priced calculator.
Answer» LET S.P. = a C.P. of 1ST calculator= a x 100/( 100 - 15 ) = a x 100/85 = 20a/17 C.P. of 2nd calculator = a x 100/( 100 + 19 ) = a x 100/119 = 100a/119 a/q 20a/17 + 100a/119 = 4800 240a/119 = 4800 a = 2380 C.P. Of 1st cal. = 20 x 2380/17 = 2800 C.P. of 2nd cal. = 4800 - 2800 = 2000 C.P. of lower priced calculator = Rs. 2000 Hope it HELP u plz mark as a brainliest

Answer»

LET S.P. = a

C.P. of 1ST calculator= a x 100/( 100 - 15 ) = a x 100/85 = 20a/17

C.P. of 2nd calculator = a x 100/( 100 + 19 ) = a x 100/119 = 100a/119

a/q

20a/17 + 100a/119 = 4800

240a/119 = 4800

a = 2380

C.P. Of 1st cal. = 20 x 2380/17 = 2800

C.P. of 2nd cal. = 4800 - 2800 = 2000

C.P. of lower priced calculator = Rs. 2000

Hope it HELP u
