Two fifth of one fourth of three seventh of a number is 15. What is half of that number ?Options: (1) 94 (2) 175 (3) 188 (4) 196

(2) 175. 3/7 of 350 is 1501/4 of 150 is 37.52/5 of 37.5 is 151/2 of 350 is 175Thanks for giving us options

2/5 * 1/4 * 3/7 * x = 156/140 * x = 153/70 * x = 153x = 15 * 703x = 1050x = 1050/3x = 350Half of 350 = 175!! (Which is number 2, same as above!)Took me a while to figure it out but I finally did

(2/5)(1/4)(3/7) = 6/140 = 3/70(3/70)x = 15, then x = 350half of x is 175.

Answer is (2) 1752/5 * 1/4 * 3/7 * x= 15x=350350/2=175therefore answer is 175.
